Bills RB James Cook, seeking extension, sits out again - ESPN

PITTSFORD, N.Y. — Buffalo Bills running back James Cook did not participate in training camp practice for a second straight day on Monday as he continues to seek a contract extension. He's in the final year of his rookie deal.

Cook briefly appeared at the team's practice not in uniform, but instead in workout gear and a beanie. He walked by the outskirt of the field, inside a portable toilet and then went back out towards the team's locker room. Cook did not appear at practice for the rest of the day.

The fourth-year running back did not participate in Sunday's practice but was on the field for the entire session. Afterward, Cook, 25, told reporters that he wasn't participating because of «business.» He had previously participated in all eight of the team's training camp practices and the three days of mandatory minicamp, but was not at the team's voluntary offseason team activities.

Bills general manager Brandon Beane said during his appearance on local radio station WGR550 on Monday morning that they did not know Cook wouldn't be practicing on Sunday until shortly before practice. At the time of the interview, about two hours before practice on Monday, Beane didn't know if Cook would be practicing on Monday.

«At the end of the day, I wish we weren't here,» Beane said on WGR550. «This is my ninth season here. We've never had a player miss due to a contract or anything like that, so that's disappointing for me. It's not something we want, not something we're looking forward to, but at the end of the day, like I said earlier, it's kind of, sometimes can be the way of the world and so we'll deal with it the best we can.»

Beane also said on Monday there has been «constant communication» between the Bills and Cook and his
