Austin Rivers picked up his fourth foul with 6:39 remaining in Duke's 68-61 win over Kansas in the championship game of the Maui Invitational.

Mike Krzyzewski replaced Rivers with Tyler Thornton and never subbed him back in. Rivers had been struggling in the second half and took several wild shots, but Krzyzewski said the benching wasn't a punishment.

"Just defensively we needed it. Austin had four, and he got banged up on his shoulder a little bit. It wasn't that we were ... he didn't do anything wrong. It was just that team out on the court was so good defensively that you didn't want to mess up with it. He's fine with it. He'll win a lot of games for us, and he has. That's why he made all-tournament team. He's played well here."
