Nick Mullins closed the gap for Southern Miss (2-1) with a 16-yard TD pass to Allenzae Staggers late in the third. Mullins completed 24 of 52 passes for 263 yards and had the Golden Eagles at the 9 with three seconds left, but was unable to connect.

Ito Smith, 131 yards rushing, ended the first half and started the second with TDs, as Southern Miss rallied to tie at 24.

Troy’s defense broke up 10 passes, forced three turnovers and had a season-high eight three-and-outs.
