With 2:24 left in Saturday's game at Texas, Oklahoma guard Buddy Hield drained a 3-pointer from the corner to put the Sooners up by two.
But on the play, Isaiah Cousins threw an elbow at Texas' Demarcus Holland.
Hield's shot counted but the technical was Cousins' second, leading to an ejection, and the Longhorns went to the line and tied it before Jordan Woodard scored OU's last 10 points to give the Sooners an 88-85 win.
Referees reviewed the play and OU coach Lon Kruger didn't offer any protest when informed of the call.
“They just said it was a collision and Isaiah got his elbow up,” Kruger said. “You can't do that.”
Early in the first half, Cousins and Texas' Isaiah Taylor had a verbal exchange that led to a double technical.
Sophomore guard Je'lon Hornbeak returned from a broken foot, playing for the first time since Dec. 8.
The plan to ease Hornbeak back into action was thwarted a bit when Woodard got in foul trouble early.
Hornbeak wound up playing 14 minutes, missing both of his shots but adding two assists.
Kruger was pleased with Hornbeak's play at the point.
