Pregame: No Allen, Pietrus for C's

The Celtics' bench will be thin Tuesday night against the Knicks as both Ray Allen (ankle) and Mickael Pietrus (knee) will miss the game.

Allen appeared set to return after joining the team in New York and going through a morning shootaround, but his sore right ankle flared after the session, according to coach Doc Rivers. Pietrus, who had offseason right knee surgery, experienced some swelling after the Celtics endured a back-to-back-to-back this past weekend, which may have contributed to his being sent home.

"I got here and the Grim Reaper -- that’s what we call [team trainer] Eddie [Lacerte] when he comes in -- and he gave me the news [on Allen]. You just roll with it; we’ll see tomorrow," Rivers told reporters in New York.

As for Pietrus, Rivers added, "[It was] probably the three days in a row. You kind of forget that he's been out so long and we threw him right back in the fire. I probably erred there, three days in a row for him; His knee swelled up, so we sent him back home, right away."

Allen has now missed 11 of the team's last 16 games. Pietrus missed 10 games while recovering from a concussion before returning for the last four games.
