What happened: Henderson sat out New England's Sunday and Monday practices with an ankle injury. Wednesday night's game against Seattle begins the 2026 regular season.
Why it matters: The absence shrinks the Patriots' backfield rotation before their first game. It also delays Henderson's 2026 debut until at least Week 2.
By the numbers: The ruling came 15 days after Henderson injured the ankle on Aug. 24.
What to watch: His participation in the next practice cycle will indicate whether the absence extends beyond one game.
