When he’s been well, Titans linebacker Colin McCarthy has been a solid presence on defense. His problem has been he hasn’t been well enough, and it will be another year before he gets another chance. According to Jim Wyatt of the Tennesseean, McCarthy appears headed for season-ending shoulder surgery. He’s still going to get a second opinion next week, but it appears the injury suffered last week against the Packers is a serious one. McCarthy was making a transition from the 4-3 to a 3-4 defense anyway, so it was going to be an uphill climb for the former team captain. Now the climb’s at least a year longer.
