Vikings cornerback Chris Cook will be taken off injured reserve Saturday and get some playing time Sunday against the Texans.
Cook has missed the last six games recovering from a broken arm. Coach Leslie Frazier said he wasn't sure how much time he'll get.
Defensive end Brian Robison returned to practice Friday, but is questionable for Sunday. Robison is fighting to push through the pain of a shoulder sprain suffered during last Sunday's victory over the Rams.
Also back at practice was left tackle Matt Kalil. He was out for some kind of illness Thursday, but is listed as probable for Sunday.
