Justin McBride had 20 points and nine rebounds for the Knights (8-6, 2-1).
Southern Methodist and No. 22 South Carolina (15-0) are the only undefeated Division I teams, but the Mustangs know they will play only 30 games this season because of a postseason ban as part of NCAA sanctions handed down last fall that included Coach Larry Brown being suspended for the team's first nine games.
The Mustangs have won all six games since Brown returned. But the 75-year-old coach wasn't on the bench after halftime Sunday because he wasn't feeling well. Brown experienced symptoms of vertigo.
