Celtics' point guard Rajon Rondo sat out practice today. Coach Doc Rivers said Rondo is "50-50" for tomorrow night's game against the Trail Blazers. Rondo has a sore right hamstring and a sore back and missed all of last Saturday's game and half of Monday's game.

He said he is still sore - it was the hammy which bothered him the most on last night - and that it will be the proverbial "gametime decision" as to whether he goes or not. If he doesn't, Rivers said he is prepared to use rookie point guard Gabe Pruitt, who generally is on the inactive list when he isn't playing for the Utah Flash in the D-League.
