The ongoing contract saga with running back James Cook took a negative turn for the Buffalo Bills. On Sunday during the team's ninth day of training camp, Cook sat out because of the ongoing negotiations.

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.
