Tennessee coach Bruce Pearl says he'll only play Volunteers that are committed to playing defense.

Pearl is preparing his team for No. 21 Memphis and the start of SEC play.

The Vols (9-4) have lost four of their last six games because of increasingly poor defense.

"We made it worse on ourselves by losing confidence in ourselves and each other," Pearl said. "You put it all together and you put yourself in a bit of a spin."

Pearl has one game to tweak the rotation himself before he begins serving an eight-game suspension for lying to NCAA investigators during an ongoing probe into recruiting practices by the Tennessee coaching staff.

"It's fixable," Pearl added. "Unfortunately, it's fixable as we start to get into the teeth and some of the more challenging parts of our schedule."
