Greg Stiemsma is the only player on the Celtics with a non-guaranteed contract, but a source says he will not be waived on Tuesday.

"I try not to get caught up in the business side once we get the season rolling," he said. 
"I think overall it's been a great opportunity. I started out hot and that's just the way the game goes, the way the season is going to go. It's going to be here and there. As long as I'm ready when I get the call."
