Junior running back Kevon Johnson scored his second touchdown of overtime on a 2-yard run Thursday, giving the Falcons a 20-14, two-OT victory over visiting Cooper in a battle for Robbinsdale school district bragging rights that involved top-10 Class 5A teams.

Cooper had the opening possession of the second OT. Its 22-yard field-goal attempt was blocked.

Both teams scored in the first OT. Johnson scored on a 5-yard run for No. 5 Armstrong (3-0), and Cooper matched it with senior quarterback Kameron Fox's 10-yard touchdown pass to junior Emmanuel Karmo.

No. 8-ranked Cooper (2-1) had a go-ahead touchdown nullified early in the fourth quarter because of an offensive pass interference penalty. It turned the ball over on downs two plays later at the Armstrong 17.

The Falcons opened the scoring when junior quarterback Dawson Franke hit Johnson with a 20-yard scoring strike over the middle on third-and-13 with 3:27 remaining in the first half.
