Ray Allen took part in Boston's shootaround this morning, but it's still not certain if he'll play tonight against the Mavericks. They Celtics didn't need him to knock off the Spurs and Rockets in their past two games.
Celtics coach Doc Rivers wouldn't commit to Allen's playing status, saying he won't play anyone who's not 100 percent.
Tony Allen is likely out after he fell hard on his back during the Houston game.
