Shemar Moore reacts as CBS cancels ‘S.W.A.T.’ after eight seasons, calling the move ‘a mistake.’ The network previously axed the show in 2023 after season 6, then reversed course with a renewal for a seventh and final season. In a surprise move, CBS extended ‘S.W.A.T.’ for an eighth season in 2024, but ET’s confirmed the show will officially wrap in May.
