Brown sustained a shoulder injury during Saturday's preseason contest at Jacksonville.
QB Patrick Mahomes connected with Brown on an 11-yard catch on the first play from scrimmage, but afterward the offseason addition appeared to favor his shoulder on the sideline. After a Harrison Butker field goal ended the Chiefs' first drive, Brown was seen making his way to the locker room. Considering it's the preseason and not the regular season, Brown likely has seen his last action of the team's exhibition opener.
