Toppin, the reigning Big 12 Player of the Year and projected first round NBA draft pick , had 20 points and eight rebounds before the injury. The Red Raiders (19-7, 9-4) would go on to lose to the Sun Devils, 70-67 , but the defeat was far less concerning than Toppin's status.

Toppin was attempting to drive to the line in transition but lost his balance and had the ball blocked out of bounds. He stayed on the ground for a period, holding his right leg and asked for trainer Mike Neal to come over and help him.

Coach Grant McCasland and Neal had to help Toppin off the floor as Toppin was not able to put his full weight on his leg.

"I just know he's really disappointed. He's such a competitor," McCasland said postgame.

Texas Tech, a No. 3 seed in USA TODAY Sports' latest bracketology , can't afford to lose Toppin, who was on his way to an All-American season. Toppin was coming off a 31-point, 13-rebound effort in Texas Tech's win over then-No. 1 Arizona on Feb. 14.

Toppin is averaging 21.8 points and 10.8 rebounds per game this season.

"Hate to see a guy go out of the game like that," ASU coach Bobby Hurley said afterward. "One of the best players in the country."
