MINNEAPOLIS - Vikings cornerback Chris Cook will need surgery on his broken right arm and will be out seven or eight weeks.
Coach Leslie Frazier said Friday that the team is planning to place Cook on revocable injured reserve following his injury Thursday night during a loss to Tampa Bay.
There is a likelihood that Cook could be out for the remainder of the regular season. But the Vikings (5-3) are holding out hope he can return for the playoffs if they qualify.
Rookie Josh Robinson will take Cook's spot in the starting lineup. Cook has been their best player in man-to-man pass coverage, so this is big loss.
Cook was hurt helping make a tackle of running back Doug Martin early in the third quarter Thursday. Martin scored on a 64-yard pass on the next play. The Bucs went on to beat the Vikings 36-17.
Cook missed most of his rookie season because of meniscus injuries in both knees. Last year (2011-2012) he spent the last 10 games away from the team after his arrest on felony assault charges after an altercation with his girlfriend. Cook was later acquitted.
He was hitting his stride this season, only to get hurt again.
