Mobile, AL (Sports Network) - Colton Cook's 28-yard field goal on the game's final play lifted Southern Utah to a 22-21 win over South Alabama at Ladd- Peebles Stadium Thursday night.

Cook kicked three field goals in the upset.
Southern Utah had pulled within 21-19 on Aaron Cantu's 2-yard touchdown pass to Anthony Norris with 6:13 left to play, but the Thunderbirds failed to tie the game on an attempt for a two-point conversion.
After holding South Alabama to a four-and-out series, the Thunderbirds regained the ball and drove 54 yards to the Jaguars' 11 in the final 4:43.
Cantu finished 13-of-24 for 183 yards. Raysean Martin rushed for 107 yards and one touchdown on 23 carries.
South Alabama was a start-up program on the FCS level in 2009. The Jaguars are in their second season as Sun Belt Conference members.
