PITTSBURGH >> Cade Klubnick sprinted 50 yards for a go-ahead touchdown with 1:16 remaining and No. 17 Clemson fended off Pittsburgh 24-20 on Saturday.

The Tigers (8-2, 7-1 ACC) had done little on the ground all day before the junior quarterback tucked the ball and raced past a handful of stunned defenders to keep Clemson’s outside hopes of reaching the ACC championship game alive.

Klubnick finished with 288 yards and two touchdown passes through the air and added 41 yards on the ground, almost all the positive yardage coming on his zig-zag through the Pitt secondary just 20 seconds after the Panthers had taken the lead on a 47-yard field goal by Ben Sauls.

No. 2 OHIO ST. 31, NORTHWESTERN 7 >> Ohio State wide receiver Carnell Tate celebrated his Chicago homecoming with two touchdown receptions against Northwestern at Wrigley Field.

No. 3 TEXAS 20, ARKANSAS 10 >> Quinn Ewers threw for 176 yards and two touchdowns and the Longhorns defense clamped down on the Razorbacks final two possessions to help secure the win.

No. 9 ALABAMA 52, MERCER 7 >> Jalen Milroe passed for two touchdowns and ran for a third in just over two quarters to help No. 9 Alabama beat FCS team Mercer.

No. 18 COLORADO 49, UTAH 24 >> Shedeur Sanders overcame a shaky start to throw three touchdown passes, LaJohntay Wester returned a punt 76 yards for a score and the Buffaloes pulled away late to beat the Utes.

Winners of four straight, the Buffaloes (8-2, 6-1 Big 12, No. 17 CFP) remain in the driver’s seat for an appearance in the conference title game and possibly a spot in the College Football Playoff.

No. 25 TULANE 35, NAVY 0 >> Makhi Hughes ran for 82 yards and two touchdowns, as the Green Wave locked up its spot in the American Athletic Conference championship game by romping to a victory over the Midshipmen.
