The Eagles have lost 25-year old inside linebacker Omar Gaither for the season due to surgery to repair a Lisfranc sprain in his left foot.  He was the leading tackler for the Eagles at the time of his injury and this further explains why the team felt the need to trade for a solid inside linebacker like Will Witherspoon.  Gaither played in 5 games for the Eagles this season and he had 30 tackles, 1.5 sacks, 4 tackles for a loss and he defensed 1 pass.
