Free-agent Keith Bulluck is one of the better free agents on the market, but he's battling a knee injury. Bulluck's agent says his knee is a non-issue after having knee surgery to repair a torn ACL. "To me, the ACL is not an issue. Players come back from those sorts of injuries all the time now," agent Gary Wichard said. "It's not the same type of injury it was 15 or 20 years ago."
