Bills GM Buddy Nix expects NT Torell Troup (back surgery) to be a full participant in Buffalo's first training camp session Thursday. "When he left here (in the spring) we watched him hitting the sled and doing all those things and it looked like he was ready to go," Nix said. A second-round pick in 2010, Troup played just 94 snaps before landing on injured reserve in Week 11 last season. He's ticketed for a rotational role.
