One big man back, another injured. So it goes for the Boston Celtics.

Nenad Krstic became the latest to go down last night, with what the Celtics fear might have been a torn right ACL. He’ll undergo an MRI on Saturday to determine the severity of the injury, and will be sidelined in the meantime. (ESPN Boston)

“I don’t know,” coach Doc Rivers said when asked about the severity of the injury. “He’s out, obviously, this weekend, then an MRI. That’s as far as I’m going to go.”

Krstic’s career has been plagued by injuries. He tore his left ACL in 2006 and has only played more than 47 games twice in the past five seasons (last season and this season).

If there was a silver lining to the injury, at least Jermaine O’Neal looked good in his return to the court. (ESPN Boston)

“That’s crazy, I told [Jermaine O'Neal] he came back right on time,” said captain Paul Pierce. “We need him. We need these bodies late in the season. Hopefully Krstic is not too hurt and he’ll be back in a few days or a week or however long he takes, but we want to be healthy going into the playoffs, bottom line. It’s good to get [O'Neal] back in here and he looked good out there. I told him he moved well. You talk about a guy who hadn’t played in two or three months. That’s a big start.”
