Glen Davis suffered a strained patella tendon in his left knee on Wednesday night and will undergo an MRI on Thursday to determine the severity of the injury.

Davis, who says he's been playing through pain in the knee for much of the season, came up hobbling after a dunk with less than a minute to play in Boston's 115-103 victory over Phoenix.

"I don't really know what's going on, but I'll get an MRI tomorrow," Davis said. "It was bothering me the whole year. I've just been tough, trying to be available for the team."

Celtics teammate Kevin Garnett expressed hope that Davis wouldn't miss time, but seemed resigned to the idea that he might.

"We're back to that injury bug and trying to maneuver around it," Garnett said. "Unfortunately, Baby's going to be out. We haven't got [a lot of time left], but hopefully he's better than the norm and he's not out for too long -- or he's [not] out period. Baby's a trooper, he's been playing hurt throughout this whole year and some of last year. He [ground] through it last year and I just hope he doesn't have to go through that this year, so hopefully he's good."
