The Aggies (17-12, 8-8) played without star guards Fabyon Harris and Shawn Smith, who've traded out starts at shooting guard for much of the season. Smith missed the game for what team spokesman Adam Quisenberry dubbed ''personal issues,'' while Harris fainted during the Aggies' earlier shootaround.
Alex Caruso turned in the Aggies' play of the year when he dribbled behind his back in the lane and then dunked over Henderson on a fast break in the decisive second half. Caruso, whose electric play brought the crowd to its feet, lifted the Aggies to a 39-33 lead with 16:48 remaining, and A&M outscored a staggered Ole Miss 32-27 the rest of the way.
The Aggies outscored the Rebels 30-24 in the paint, and their 50.9 percent from the field (27 of 53) marked their best effort in seven contests.
Jordan Green earned the start in the absence of Harris and Smith and turned in a career high 16 points. After fainting, a conscious Harris was taken to an area hospital, and was expected to be held overnight for observation, Quisenberry said.
A&M, in trying to make the postseason for the first time in coach Billy Kennedy's three seasons, has won four of its last six games, and rebounded strongly from a 68-49 setback at LSU on Wednesday.
