Sam Cassell was cleared to play against the Mavericks on Sunday, but Kevin McHale held him back.

Cassell had already missed the past six games after reinjuring a hamstring, and the Wolves are 4-2 in those games.

McHale has talked about the difficulty of mixing players back into a rotation that has changed since McHale has taken over for Flip Saunders.

Cassell has admitted he has grown frustrated while waiting for McHale's approval to return.

"No doubt about it," Cassell said after Saturday's practice. "I just work here. He makes all the decisions. I just work here. I have to be ready, show him that I'm ready."
