Marshall Faulk’s knee isn’t right. An MRI shows, in addition to a deep bone bruise, Faulk has been playing with loose bodies in the knee. Coach Mike Martz says for now, surgery can wait until the offseason. Arthroscopic surgery would fix the problem, but Faulk can continue playing unless one of the loose bodies becomes lodged in the wrong spot. Faulk is bothered more by the bone bruise than anything else.
