GLENDALE, Ariz. (AP) Arizona Cardinals coach Bruce Arians says wide receiver John Brown will be sidelined while undergoing the concussion protocol.
Brown was hurt when his head slammed into the turf during a collision with cornerback Patrick Peterson at Sunday's practice.
Cornerback Mike Jenkins broke a bone in his right hand in practice on Saturday and, Arians said, was to undergo surgery Monday. Arians said Jenkins should be back practicing while wearing a cast in two to three weeks.
Arians said right guard Evan Mathis left Sunday's practice due to left leg fatigue. Mathis underwent ankle surgery on the same leg in the offseason.
Mathis, running back Chris Johnson and backup quarterback Drew Stanton were given a veteran's day off from practice Monday.
