Buffalo Bills running back James Cook put aside his contract concerns — and avoided the potential of being fined — by attending the start of the team’s three-day mandatory series of practices on Tuesday.

James Cook is at Buffalo Bills minicamp, and Sean McDermott is ecstatic about it. The Bills running back, who has been the subject of trade scuttlebutt amid contract disputes, earned praise from the veteran Buffalo coach for reporting to mandatory practices this week despite his frustrations of not getting a new deal.
