Minnesota Vikings cornerback Chris Cook underwent further post-concussion testing on Tuesday and did not pass, according to ESPN 1500's Tom Pelissero, making him unlikely to see action in Friday night's matchup with the San Diego Chargers. Vikings coach Leslie Frazier said that he hoped the third-year player out of Virginia, who is expected to be a starter in 2012, could get in some practice time on Wednesday. Cook was injured during preseason action on Friday night in a collision with Buffalo Bills receiver Stevie Johnson.
In Cook's absence, veteran Chris Carr and rookie Josh Robinson will receive more playing time. Carr is in his seventh NFL season, after stints with the Oakland Raiders, Baltimore Ravens and Tennessee Titans, and has played most of the snaps this preseason as the third defensive back in the Vikings' nickel package. Robinson, a third-round pick in the 2012 draft out of Central Florida, impressed the coaching staff with his play on Friday night.
