Mills has one year remaining on his rookie contract entering the 2024 offseason. He completed 18 of 39 passes for 173 yards and two touchdowns over six regular-season games in 2023.
Mills operated as the primary backup when C.J. Stroud was healthy and starting, but when the No. 1 quarterback couldn't go in Weeks 15 and 16 due to a concussion, the Texans used Case Keenum as their starter. Both backup QBs are under contract for 2024, although Keenum's cap hit would be minimal if he were to be released.
