Groin issue. If he isn't needed this weekend, don't use him. Those injuries need time to heal, they nag. I strained mine pretty good earlier this season and needed about 3 weeks rest before I was pain free. What he needs to do is as long as he is mobile, he needs to be out there with his group helping coach those guys up. He's a captain and a vocal leader. If you can't lead from the field find another way to get in and help. Hope we get him back soon though, because he is a talented guy.
