Buffalo Bills GM Brandon Beane says he was disappointed by running back James Cook's decision to quit practicing at training camp over contract dispute.

Amid contract negotiations with the Buffalo Bills, running back James Cook has opted to stage a hold-in during the team's training camp.

Cornerback Max Hairston suffered a knee injury that will keep him out for multiple weeks, and wide receiver Khalil Shakir suffered a high ankle sprain that could cause him to miss Week 1 against the Baltimore Ravens. Now, the Bills are dealing with yet another issue.
