TAMPA, Florida (Ticker) -- South Florida made its first Conference USA home game an auspicious one.

Santiago Gramatica booted a 26-yard field goal in the second overtime as the Bulls posted a 31-28 victory over previously unbeaten Louisville.

South Florida (3-1, 2-0 C-USA) won its conference opener last week at Army, 28-7. Hosting its first game in its new league at Raymond James Stadium, the Bulls got a one-yard touchdown run by Clenton Crossley on fourth down with 10 seconds remaining in regulation to tie the game, 21-21.

Louisville had taken a 21-14 lead on Michael Bush's five-yard TD pass to quarterback Stefan LeFors with 8:19 left in the fourth quarter.

Each team traded touchdowns in the first overtime and South Florida linebacker Devon Davis came up with a big play by intercepting LeFors on Louisville's possession in the second overtime. The Bulls picked up one first down before Gramatica came on to kick the game-winner.

Louisville (4-1, 0-1) suffered its first loss in the first meeting between the schools. It also was the first loss for coach Bobby Petrino.

LeFors completed 19-of-39 passes for 267 yards, one touchdown and two interceptions. The Cardinals rushed for 187 yards, including a 67-yard TD run by Lionel Gates in the first quarter.

South Florida's Ronnie Banks completed 26-of-47 passes for 256 yards with a touchdown and three interceptions.
