MADISON, Wis. — Leo Chenal recorded 17 tackles and set up a touchdown with a sack that forced a fumble, leading Wisconsin to a 20-14 victory over Army on Saturday night.

Army trailed 13-7 and had the ball when Chenal delivered a punishing hit that knocked the ball loose from quarterback Tyhier Tyler. Wisconsin's Keeanu Benton recovered the fumble at Army's 1-yard line with 2:55 remaining.

On the next play, Graham Mertz scored on a quarterback keeper. Mertz also scored on a 5-yard keeper in the second quarter, giving him his first two touchdown runs of the season.

Army cut the lead to 20-14 on A.J. Howard's 6-yard touchdown run with 38 seconds left, but Jack Sanborn recovered the ensuing onside kick to seal the victory.

Wisconsin's Braelon Allen rushed for 108 yards on 16 carries, including a 33-yard touchdown.

This marked the second straight game in which Allen rushed for at least 100 yards. The 17-year-old freshman ran for 131 yards and a touchdown on 18 carries last week in a 24-0 victory at Illinois.

Army (4-2) played a second straight game without usual starting quarterback Christian Anderson, who is dealing with a shoulder injury. The Black Knights lost 28-16 to Ball State without Anderson two weeks ago.

Tyler and Jabari Laws both played quarterback in Anderson's absence. Tyler started, played most of the game and rushed for 90 yards on 17 carries. Laws had all of Army's pass attempts and went 5 of 6 for 87 yards.

Wisconsin (3-3) led 13-0 at halftime and outgained Army 230-48 in the first two periods before the Black Knights rallied, thanks to Tyler's tenacity.

Tyler took a big hit while executing a pitch late in the third quarter and stayed on the ground for a few minutes before walking to the sideline under his own power. But he sat out just one play before returning to the game and promptly racing 36 yards on a keeper that gave Army first-and-goal.

Two plays later, Tyler ran into the end zone from 5 yards out on third-and-goal to cut Wisconsin's lead to 13-7 with 11:22 remaining.

Sanborn also came up big with 12 tackles and a couple of big plays on special teams. Before recovering an onside kick in the closing seconds, Sanborn took a snap and ran eight yards on a successful fake punt attempt that set up a second-quarter touchdown.

Wisconsin returns to Big Ten league play on the road next Saturday at Purdue. Kickoff is slated for 2 p.m. on Big Ten Network.
