The 2026 Indiana high school football season opens this week, and the schedule wastes no time delivering matchups worth circling.
There is a rematch of last November’s Class 4A state championship, a meeting between two programs that played for state titles in different classifications, several cross-class matchups and early tests for teams expected to contend deep into the fall.
Some programs are also opening a new chapter after moving classifications for the 2026 season.
Indiana Preps has identified 12 games that matter most on opening weekend.
Here is what to watch.
Center Grove vs. Warren Central
Class 6A | Friday, August 21
Last season: Center Grove 10-2 | Warren Central 9-5
There is already postseason history attached to this Week 1 matchup.
Warren Central stunned Center Grove in the 2025 regional, erasing an early 17-0 deficit to defeat the Trojans 24-21. The Warriors continued their postseason run into the Class 6A semi-state before falling to eventual state champion Brownsburg.
Now they go back to Center Grove.
Warren Central enters the season ranked No. 2 in the Indiana Preps preseason Top 25, while Center Grove checks in at No. 4.
It is rare for an opening-week matchup to carry the residue of a postseason elimination from the previous season. This one does.
Center Grove gets the first opportunity to answer. Warren Central gets the opportunity to prove last November was no exception.
Eastside vs. South Adams
Class 2A vs. Class 1A | Friday, August 21
Last season: Eastside 9-3 | South Adams 10-4
South Adams put together one of the deeper postseason runs in northeast Indiana last fall, advancing all the way to the Class 1A semi-state before its season ended against Pioneer.
Eastside’s season also ended at the hands of a northeast Indiana power. The Blazers reached the Class 2A sectional championship before falling 53-32 to Adams Central.
That gives this opener more postseason experience than the classifications might suggest.
South Adams brings back a program that knows what it takes to play into late November. Eastside comes off a nine-win campaign and gets an opportunity immediately to measure itself against a team that was among the final four remaining in Class 1A last season.
Riverton Parke vs. Linton-Stockton
Class 1A vs. Class 2A | Friday, August 21
Last season: Riverton Parke 11-1 | Linton-Stockton 9-4
Riverton Parke was one of the biggest stories in Class 1A last season.
The Panthers opened 11-0 before their season ended with a 29-21 overtime loss to eventual state champion South Putnam in the sectional championship.
Now Riverton Parke enters 2026 as the Indiana Preps preseason No. 1 team in Class 1A.
The first test comes against a Linton-Stockton program that won nine games last fall and enters the new season competing in Class 2A.
For Riverton Parke, this is an immediate opportunity to validate its preseason billing. For Linton, it is a chance to hand the top-ranked 1A team a loss before either program gets comfortable.
Andrean vs. Merrillville
Class 3A vs. Class 6A | Friday, August 21
Last season: Andrean 13-1 | Merrillville 11-3
Few Week 1 matchups feature résumés like this.
Andrean won the 2025 Class 2A state championship, shutting out Brownstown Central 7-0 at Lucas Oil Stadium. Merrillville reached the Class 5A championship game before falling 38-17 to New Palestine.
Now both enter 2026 in new classifications.
Andrean moves into Class 3A under the IHSAA Tournament Success Factor, while Merrillville enters the Class 6A field.
That means the defending 2A state champion opens its season against a program coming off a state-finals appearance three classifications above it.
Andrean returns several names worth tracking, including linebacker Javier McCoy, quarterback Dylan Gore and receiver Tyler Vo. Merrillville will look to reload after coming within one victory of a championship last November, with Indiana Preps preseason All-Indiana selection Michael Hill Jr. among the players expected to take on an important role.
A combined 24 wins. Two 2025 state finalists. Two programs entering new classifications.
There may not be a better measuring-stick game in Indiana on opening night.
Evansville North vs. Castle
Class 5A | Friday, August 21
Last season: Evansville North 8-3 | Castle 6-4
Evansville North came within one possession of a sectional championship last fall.
The Huskies finished 8-3 and saw their season end in a 15-10 loss to Floyd Central in the Class 5A sectional final.
Castle finished 6-4, with its postseason ending against that same Floyd Central program in the opening round.
That gives this matchup a clear early-season storyline.
Evansville North wants to establish itself as one of the teams capable of breaking through in a southern Indiana 5A field. Castle gets an immediate opportunity to show that 2026 can look different from the way 2025 ended.
Week 1 will give us the first indication of where both programs belong in the southwest Indiana conversation.
East Central vs. Lawrenceburg
Class 4A vs. Class 3A | Friday, August 21
Last season: East Central 9-3 | Lawrenceburg 10-2
Few rivalries in southeastern Indiana need much introduction.
East Central and Lawrenceburg meet again in Week 1 with both programs coming off strong seasons and both carrying expectations into 2026.
East Central returns to Class 4A after competing in 5A under the Tournament Success Factor. The Trojans open the season as one of the programs expected to factor heavily into the 4A championship conversation.
Lawrenceburg enters 2026 in Class 3A after a 10-win season.
Classification rarely means much once these two line up against each other.
East Central gets an immediate test as it begins its return to 4A. Lawrenceburg gets the opportunity to make an early statement against one of the state’s most established programs.
The rivalry handles the rest.
Bishop Dwenger vs. Roncalli
Class 4A | Friday, August 21
Last season: Bishop Dwenger 13-2 | Roncalli 11-4
You could not script a much better Week 1 storyline.
Bishop Dwenger defeated Roncalli 36-29 in the 2025 Class 4A state championship game.
Now they meet again on the first Friday of the 2026 season.
There is another layer to it: Roncalli defeated Dwenger 3-0 in Week 1 last season before the Saints eventually returned the favor with a state championship on the line.
So this is not simply a title-game rematch.
It is the third chapter of a developing matchup between two programs that split two dramatically different games last season.
Bishop Dwenger begins its title defense against the team it beat to win it all.
Roncalli does not have to wait until November for another shot.
For pure context, there may not be a more compelling game on the opening-week schedule.
Lafayette Jeff vs. Bishop Chatard
Class 5A vs. Class 4A | Friday, August 21
Last season: Lafayette Jeff 10-2 | Bishop Chatard 9-3
Lafayette Jeff carried one of the state’s hottest teams into the 2025 postseason and eventually captured a sectional championship before falling 47-45 to Concord in the Class 5A regional.
The Bronchos now open 2026 against one of Indiana’s most established postseason programs.
Bishop Chatard has built its reputation around physical football, disciplined defense and an expectation that its season extends well beyond October.
That makes this a valuable opening test for both sides.
Lafayette Jeff gets an opportunity to show its 10-win campaign was something it can build upon. Chatard gets a 5A opponent immediately as it begins another season with postseason expectations.
Cross-classification games are most interesting when both teams have something legitimate to learn from them.
This one qualifies.
Carroll vs. Hamilton Southeastern
Class 6A | Friday, August 21
Last season: Carroll 9-4 | Hamilton Southeastern 6-5
Carroll enters 2026 after winning a sectional championship and finishing 9-4 last season.
The Chargers are No. 10 in the Indiana Preps preseason Top 25 and once again enter the year as one of northeast Indiana’s most prominent 6A programs.
Hamilton Southeastern comes off a 6-5 season and faces the challenge of navigating one of the state’s deepest football conferences.
That makes Week 1 important for both.
Carroll can immediately test its preseason ranking against an HCC opponent. Hamilton Southeastern gets an opportunity to establish a different tone after an up-and-down 2025 campaign.
Nobody wins anything significant in August, but games like this can tell us quickly which direction a season is headed.
Gibson Southern vs. Floyd Central
Class 3A vs. Class 5A | Friday, August 21
Last season: Gibson Southern 12-2 | Floyd Central 10-2
Twenty-two combined wins from last season make this one difficult to overlook.
Gibson Southern finished 12-2 and again established itself as one of southern Indiana’s strongest programs.
Floyd Central won 10 games, defeated Evansville North 15-10 for a sectional championship and advanced to the Class 5A regional before falling to Bloomington South.
Now they meet immediately.
Gibson Southern gets an opportunity to test itself against a successful 5A opponent. Floyd Central gets a 12-win program before beginning another run through its own classification.
For two teams accustomed to expecting more than simply a winning season, this is exactly the kind of opener that can expose weaknesses early enough to correct them.
Carmel vs. Fishers
Class 6A | Friday, August 21
Last season: Carmel 9-2 | Fishers 8-4
Two of Hamilton County’s largest programs meet in a high-profile non-conference opener.
Carmel enters the season ranked No. 5 in the Indiana Preps preseason Top 25 after a nine-win campaign in 2025.
Fishers finished 8-4 and again showed it could compete in a loaded Hoosier Crossroads Conference.
Although this game does not count toward the HCC standings, it offers Fishers an immediate test against one of the state’s traditional powers and gives Carmel an opportunity to establish itself against a program accustomed to seeing quality 6A competition every week.
There are no conference implications attached.
There does not need to be.
Carmel-Fishers attracts attention on its own.
Bishop Luers vs. Adams Central
Class 4A vs. Class 3A | Friday, August 21
Last season: Bishop Luers 9-6 | Adams Central 13-1
The records only tell part of the story here.
Bishop Luers finished 9-6 because its season lasted all the way to Lucas Oil Stadium. The Knights reached the 2025 Class 3A state championship game before falling 29-14 to undefeated Cascade.
Adams Central went 13-1 and made a deep run of its own in Class 2A. The Flying Jets defeated Eastside 53-32, continued through the regional round and eventually saw their season end with a 24-19 loss to eventual state champion Andrean in the semi-state.
Now both programs move up.
Bishop Luers enters Class 4A for 2026, while Adams Central moves into Class 3A.
That makes this traditional northeast Indiana matchup particularly interesting.
A 2025 state runner-up against a 13-win semi-state team. Two programs beginning life in higher classifications. Two teams with postseason expectations that extend well beyond Week 1.
This is not simply an opener.
It is the first indication of how two of northeast Indiana’s most accomplished programs will handle their new surroundings.
Opening Night Has Something to Say
Week 1 does not decide state championships.
It can start conversations about who might eventually compete for one.
Bishop Dwenger and Roncalli waste no time revisiting last November’s 4A championship. Andrean and Merrillville bring state-finals résumés into one of Northwest Indiana’s biggest opening-night games. Warren Central returns to the place where Center Grove gets its first opportunity to respond to last year’s regional upset.
Elsewhere, programs moving into new classifications get immediate measuring sticks, preseason contenders have their first opportunity to justify the expectations surrounding them and several teams coming off deep postseason runs meet opponents capable of exposing weaknesses early.
That is what opening weekend should provide.
The rankings will move. Expectations will change. A few teams we think we know will look different by Friday night.
Football is back.
Now we find out who is ready.
