What happened: The Indianapolis Colts placed defensive end Arden Key on injured reserve Saturday. The team also temporarily elevated wide receiver Nick Westbrook-Ikhine from the practice squad.

Why it matters: Key sustained a hamstring injury during last week's victory over the Washington Commanders in London. The roster move guarantees the veteran pass rusher will miss a minimum of four weeks before he becomes eligible to return to action.

What to watch: Westbrook-Ikhine will be available for his third game of the year when the Colts take the field on Sunday.
