Stefan Moody scored 26 points and led Mississippi's comeback from a 17-point halftime deficit to a 94-90 victory over BYU on Tuesday night in the NCAA Tournament's First Four.

The Rebels (21-12) trailed until Moody led a 15-2 run midway through the second half. He hit a late 3-pointer that helped finish off the tournament's first big comeback.

Ole Miss goes to Jacksonville, Florida, to play sixth-seeded Xavier on Thursday afternoon in the East Region.

"I thought we were so tentative," coach Andy Kennedy said. "We wanted to impose our will to start the second half. We chopped it in half pretty quickly, our guys start believing, the ball started going in, and good things happen."

BYU (25-10) pulled off the biggest comeback in NCAA Tournament history in Dayton three years ago, rallying from a 25-point first-half deficit to a 78-72 win over Iona. This time, the Cougars couldn't hold the big lead.

Tyler Haws, BYU's all-time leading scorer, had 33 points, going 13 of 23 from the field. He missed a 3-pointer as BYU tried to catch up in the closing seconds. It was the first time this season that the Cougars lost after leading by 17 points.

Haws had 19 points in the first half, helping the Cougars pull ahead 49-32. Moody got the Rebels' guard-driven offense going midway through the second half, when three BYU players picked up their fourth fouls and things opened up near the basket.

M.J. Rhett added 20 points for Ole Miss, including a pair of three-point plays and a dunk during the go-ahead run.

Chase Fischer put the Cougars ahead 8-0, making a reverse layup and a pair of 3s. Ole Miss missed 15 of its first 19 shots overall as BYU took control. Fischer finished with 23 points, going 6 of 12 from beyond the arc.
