From Vaughn McClure: ""He has been in surgery to stabilize his vertebrae," Smith said. "He's out, of course, this year. But just looking to the future, it looks bright for him, of course, to play and to get back out there. So we're encouraged by that." According to a league source, Knox cracked a facet joint, which help keep the spinal column stable. He should be recovered within three to four months, according to the source." UPDATE: Zack Zaidman reporting that, while the team is optimistic of Knox's recovery, it's unknown whether he'll be ready for training camp in 2012.
