Cook (chest) was a limited participant in Thursday's practice.
Despite having his reps capped for the second straight day, the running back remains optimistic that he'll be able to play Sunday against the Lions, with coach Mike Zimmer also supporting that notion, per Chris Tomasson of the St. Paul Pioneer Press. Even if Cook ultimately gains clearance to suit up this weekend, the Vikings could choose to act conservatively with his workload, given his injury history along with the fact that Minnesota is a double-digit favorite in Week 14 while hosting a 3-8-1 Lions squad that's down to its third-string quarterback in David Blough.
