No. 25 Mississippi 44, Texas 23: Bo Wallace threw for two touchdowns and ran for another and the visiting Rebels scored 27 unanswered points in the second half to go 3-0 for the first time since 1989.

Wallace’s 15-yard touchdown run midway through the third quarter put the Rebels (3-0) ahead 24-23, then he made a nifty play-action fake and hit Evan Engram for a 17-yard score. Jeff Scott’s 73-yard punt return blew it open with nine seconds remaining in the period.

Texas (1-2) lost its second straight as new defensive coordinator Greg Robinson was unable to thwart Wallace or Scott, who ran for 162 yards and a touchdown on 20 carries.

Longhorns senior Case McCoy, playing for the injured David Ash, made his seventh career start and hit 24-of-36 throws for 196 yards and touchdown. But he could not lead a scoring drive after intermission. Johnathan Gray ran for 91 yards and a touchdown.

After giving up 550 rushing yards last week, Texas allowed 272 yards on the ground, an average of 6.0 per carry.
