Chris Bosh could be out for a few weeks with a strained calf injury.

Bosh isn't sure when the injury occurred. 

Bosh hadn't missed a game this season until Sunday, and he pointed to simple "wear and tear" as a possible reason for the strain.

If he tries to play through the injury, he said it could worsen and "the muscle could tear away from the bone."

"It's disappointing," Bosh said. "Usually you know when something gives and you kind of feel it over the course of a game and you can point to a specific play when you felt something tweak, or whatever, but unfortunately that didn't happen for me. I guess it's a wear and tear thing. It kind of sprung up on me, and you just have to deal with the tough times right now."
