Jefferson (calf) underwent an MRI and the results showed no structural damage, Rick Bonnell of the Charlotte Observer reports.

Analysis:

Jefferson said he heard a "pop" in his calf during Wednesday's game, but judging from the MRI it appears he's avoided a major injury. That said, the team has already ruled him out for Friday's game, and he'll undergo further tests as the team seeks a diagnosis. Bismack Biyombo will start at center in Jefferson's place.
