Bills sign DT Casey Walker, release DE Cedric Reed

You may have heard that today was the first day of training camp for the Buffalo Bills, but the roster is far from settled. In fact, it took one practice for the team to decide to shake things up.

#Bills sign DL Casey Walker and release DL Cedric Reed.

Walker, 26, is on his fourth NFL team since 2014. He saw his most extensive action with the Patriots that season, appearing in five games and starting in one, a 37-22 victory over our beloved Buffalo Bills in October of 2014. He was demoted to the practice squad later that season before being signed by the Baltimore Ravens, where he played in one game before being released. He appeared in two games at the end of the season for the Dallas Cowboys, recording both of his tackles in their 16-6 loss to our beloved Buffalo Bills (again). Now, he'll have a chance to make the roster for the Bills instead of one of their opponents.

Reed, 23, was a UDFA pickup by the Bills last season. He spent 2015 on the practice squad, but had an opportunity to advance with the organization, given the team's newfound need for a pass-rushing end with both Shaq Lawson and Manny Lawson on the shelf at the moment. If he couldn't even stick through the first day of camp, though, he probably wasn't someone who was going to make the roster in the long run.
