Kansas City Chiefs defensive end Frank Clark was arrested in Los Angeles after police saw a submachine gun in his car.
Clark, 28, was pulled over for a vehicle violation south of downtown at about 9:20 p.m. Sunday, the LAPD said.
Officers noticed a bag with an Uzi sticking out in plain sight in the car. Clark was then arrested on suspicion of having a concealed firearm in a vehicle.
He was booked into Los Angeles County jail and released Monday afternoon on $35,000 bond.
