Summers-Gavin's knee injury just a bruise

California offensive lineman Matt Summers-Gavin suffered a bone bruise and not a serious knee injury as was originally feared, an MRI revealed Monday. He will be out about two weeks.

"It's good news," Cal coach Jeff Tedford told reporters. "Any time you see something like that you just hold your breath."

Summers-Gavin, an all-conference candidate, will return to left guard when he comes back after playing left tackle during the spring. Mitchell Schwartz will move over to left tackle from the right side.

Tedford said he expects Summers-Gavin to be ready to play in the opener against UC Davis on Sept. 4.

"I would think so," Tedford said. "It's not guaranteed, but I would think so."
