WALTHAM -- Celtics forward Brian Scalabrine was taken to New England Baptist Hospital after suffering a concussion at practice today, and coach Doc Rivers said he expects the forward to be out for an extended period of time.
Scalabrine originally suffered a concussion against Dallas last Sunday and received another when he bumped into teammate Patrick O'Bryant while trying to get a rebound at practice today.
Scalabrine is averaging 3.1 points and 1.3 rebounds this season.
"He got hit in the head and just had a mild concussion," Rivers said. "I don't know if he is out, but it's close. He'll be out probably for quite some time."
Rivers said he could activate guard Tony Allen tomorrow night against Sacramento after he missed the past 11 games with a sprained right ankle. Allen practiced today. Rivers said he has been cautious with Allen’s return to ensure he is completely healed.
“Tony looked good actually,” Rivers said. “He ran well, moved well. You could tell he was in terrible shape and that was what he was concerned by. He said, ‘My, after three minutes I was dying.’ We said, ‘We’ll play you three minutes.’ With Scal out, Tony may have to play [more] tomorrow.”
