Cleveland Browns running back Peyton Hillis will miss a couple of weeks after re-injuring his hamstring during Friday's practice.

An MRI was performed, and a source told the Cleveland Plain Dealer that Hillis had significantly aggravated the muscle.

Hillis grabbed his left hamstring at the end of a rushing play, fired the football to the ground in frustration and limped halfway down the practice field where he received assistancce from the training staff.

Hillis has been plagued by the hamstring problem for nearly the entire season, prompting Coach Pat Shurmur to say that if Hillis cannot play Sunday against Houston that the Browns will "move on."

Montario Hardesty is hurt as well, leaving the Browns to likely go with former Texan Chris Ogbonnaya with newly-signed Thomas Clayton backing him up.
