Gibbs, who completed 18 of 38 passes, threw touchdowns of 23 and 9 yards in the first half as the Braves (4-6, 4-4) took a 14-10 lead into halftime.
Rudy Johnson connected with James Davis from 22 yards out on Texas Southern's first drive of the second half to give the Tigers (2-8, 2-6) their first lead of the game, 17-14.
After Walker's first rushing touchdown put Alcorn State back ahead 21-17, Johnson broke a 46-yard run to give the Tigers a 24-21 fourth-quarter lead.
But Alcorn was not finished, as Walker's second touchdown, this time from 1-yard out, swung the lead back into Alcorn State's favor, 27-24, and Gibbs' third touchdown pass put the game away.
