Arizona Cardinals wide receiver John Brown is out of practice after suffering a concussion on Sunday, coach Bruce Arians announced.
Brown is currently going through concussion protocol and can return to practice once he is cleared through a number of tests.
The 26-year-old comes into camp as one of Arizona’s top receivers, along with veteran Larry Fitzgerald and Michael Floyd.
Brown had his breakout season for the Cardinals in 2015, hauling in 65 catches for 1,003 yards and seven touchdowns.
He is entering his third season with Arizona after being drafted by the team in the third round of the 2014 draft.
