Minnesota Vikings cornerback Chris Cook and tight end Kyle Rudolph both left Friday night's preseason game vs. the Buffalo Bills with possible concussions. Both were given concussion tests on the sideline early in the second quarter and have not returned to the game.
Rudolph, a second round pick in 2011, missed four games last season while catching 26 balls for 249 yards. Cook, a 2010 second round pick and one of Minnesota's key defenders, has only played in 12 games in his first two seasons. Last season, Cook missed most of Minnesota's season after being arrested for domestic assault.
