Bills general manager Brandon Beane appeared on the WGR 550 morning show on Monday. He said Cook’s decision to sit out came as a surprise. “It’s not something we were fully aware of until shortly before practice,” Beane said. “I get it. I understand it’s the world we’re in, I guess, of how players want to respond and things like that.”

The contract situation surrounding Buffalo Bills running back James Cook, which was previously dimmed, has been rekindled following his non-participation during practice on Sunday.

When Cook was asked why he didn't practice on Sunday, he responded by saying it was "business." As the Bills took the practice field on Monday, Cook again was not in uniform . It's no secret that Cook seeks a contract extension.
