Ray Allen, Mickael Pietrus remain out for Boston Celtics

Celtics shooting guard Ray Allen will miss his third straight game, Monday night in Charlotte, because of a sprained ankle. He also missed Boston’s loss on Friday night to the Philadelphia 76ers and Sunday night’s game against Washington.

Allen initially injured the ankle during a March 11 game against the Lakers in Los Angeles, but continued to play through the injury until Friday, the Boston Herald notes. The results of the MRI Allen had on Saturday, however, were not shared with Doc Rivers, which the coach interpreted as positive news.

Boston forward Mickael Pietrus, meanwhile, is out indefinitely with the concussion he suffered in a scary fall to the floor Friday in Philadelphia. Per the NBA’s concussion policy, Pietrus must be symptom-free for 24 hours before he is allowed to play.

“He has a concussion, and he’s not even ready to take a test yet,” Rivers said, per the Herald. “He sounds great. He sounds just like Mickael. I don’t even understand what he’s saying. We didn’t talk about playing, we just talked. I have no idea when he’ll be back.”
