The Panthers elevated Boone to the active roster Saturday, David Newton of ESPN.com reports.
With Jonathon Brooks (knee) set to miss at least the first four games of the regular season while on the NFI list, Boone will serve as the fourth running back on the Panthers' depth chart for Sunday's game against the Saints behind Chuba Hubbard, Miles Sanders and Raheem Blackshear. Boone appeared in nine regular-season games for the Texans in 2023, finishing with five carries for 23 yards and seven catches (on nine targets) for 40 yards.
