"Wide receivers Percy Harvin and Bernard Berrian are active for today's game against the Bears.

Harvin missed two days of practice this week while dealing with migraines and was listed as questionable. Berrian also was questionable after being added to the injury report on Friday because of a groin injury.

No real surprises with the Vikings inactives. Asher Allen (concussion) and safety Jamarca Sanford (hamstring) are not playing after being listed as doubtful. Neither player practiced this week.

Rookie Chris Cook will start in Allen's place at right cornerback. Cook has played on the outside in nickel situations but this is his first start as the regular right corner."
