The Minnesota Vikings are in the thick of the playoff chase and their head coach believes they have the formula to win championships. Punter Chris Kluwe was fined for a uniform infraction. Chris Cook is on track to return from a broken arm in Week 16. The Vikings replaced wide receiver Percy Harvin on the 53-man roster with offensive tackle Troy Kropog. Minnesota signed tight end LaMark Brown to the practice squad to take Kropog’s spot.
