Buffalo Bills reserve defensive lineman Torell Troup has missed practice due to a nagging back injury, which leaves his status uncertain for Sunday’s game against the Philadelphia Eagles. Coach Chan Gailey says the back pain will make it difficult for Troup to play this weekend, when Buffalo (3-1) hosts Philadelphia (1-3). Troup had only returned in a 23-20 loss at Cincinnati last weekend after the back injury forced him to miss the first three games of the season. Source: Yahoo! Sports
