What happened: Indianapolis downgraded Allen to out for Sunday's game in London against Washington because of a groin injury. The change came a day before kickoff after the Colts had not ruled anyone out earlier in the week.

Why it matters: Allen's absence strips a veteran option from the Colts' receiving group heading into an overseas matchup. It also forces Indianapolis to adjust its target share and game plan on short notice against Washington.

What to watch: Indianapolis will set its final receiver rotation when Sunday's inactive list is released. The Colts' next practice report will show whether Allen's status changes after the London game.
