Gilman has been ruled out for the rest of Saturday's preseason game against the Buccaneers due to a back injury.
Gilman may have picked up the injury during pregame warmups, which will prevent him from suiting up for Saturday's exhibition contest. He'll undergo more tests to determine the severity of the injury, but it could prevent him from playing in the Chiefs' preseason finale against the Seahawks this Friday. Xavier Nwankpa and Jaden Hicks will start at safety in Gilman's absence, with Christian Roland-Wallace sliding in as the slot corner.
