Nick Barnett is getting a second-opinion on his injured wrist, but the team is not expecting good news and is preparing to be without him for the rest of the season, a league source said Thursday. Barnett was injured during Sunday's 28-26 victory over the Detroit Lions and X-rays during the game were negative. Further tests showed damage that confirmed reports that Barnett likely will require season-ending surgery. Desmond Bishop likely will move into Barnett's spot, the source said.
