The Texans waived Mapu (undisclosed) with an injury designation Monday, Aaron Wilson of KPRC 2 Houston reports.
Mapu may have picked up an injury during the Texans' 22-20 preseason loss to the Raiders on Thursday, when he accrued four tackles. The nature of Mapu's injury isn't clear, but if he clears waivers, then he would revert to injured reserve and be forced to sit for the entire 2026 season unless an injury settlement is reached with Houston.
