The two legendary powerhouse programs will meet Friday night in the Class 4A semifinals at Putnam City High School.
Ada routed Cleveland 41-7 in the quarterfinals, while Clinton pulled off a road upset, 20-10 over Cascia Hall.
The other side of the 4A bracket isn't too shabby, either. Defending 4A champ Wagoner will face last year's 3A champion Anadarko on Friday night at Langston University.
DAVIS OVERCOMES HISTORY VS. MILLWOOD
Davis and Millwood had met three times in the playoffs before last Friday night, and Millwood had won all three. That included a state championship meeting and Millwood's upset at Davis in last year's second round.
Davis finally found a way to take down the Falcons with a 42-28 win, but it certainly wasn't easy Friday.
Millwood jumped to a 22-0 lead in the second quarter, but Davis finally got its run game going.
Braden Ruth rushed for 175 yards on 12 carries with two touchdowns, and quarterback Alec Heatherington added three more scores. The Davis defense added four interceptions to stunt the Millwood offense as well.
Davis will go on the road to Adair this Friday night for a Class 2A quarterfinal meeting between undefeated teams.
