WEST POINT — Army let a fourth-quarter lead slip away Saturday, falling to South Florida 28-24 at Michie Stadium in front of 23,670 fans on a sunny afternoon, as the Bulls scored twice in the final five minutes to complete the comeback.

Army built its lead behind quarterback Cale Hellums and a strong ground game led by Godspower Nwawuihe, who paced the Black Knights with 94 rushing yards. Zach Mundell led the way through the air with 47 receiving yards.

The Black Knights carried a 10-point lead into the fourth quarter before South Florida rallied. Quarterback Michael Van Buren Jr. accounted for all four Bulls touchdowns, finishing 19 of 30 passing for 239 yards to go with 45 rushing yards on the ground.

The go-ahead score came on fourth down with 19 seconds left, when Van Buren connected with Joshua Porter on a 38-yard touchdown pass to complete the rally.

The loss drops Army to 1-1 on the season after opening with a 59-3 win over Bryant. South Florida improved to 2-0 and picked up its first win at West Point since 2003, in the two teams’ first meeting as members of the American Conference. Army plays next at Temple.
