What happened: Indianapolis Colts wide receiver Keenan Allen is expected to play against the Pittsburgh Steelers on Sunday. The veteran is returning from a groin injury that kept him out of action last week.

Why it matters: Allen's return provides a boost for a 2-5 Colts offense looking to build off their recent win over Washington. Indianapolis faces a 3-4 Steelers team as both squads attempt to improve their standing.

What to watch: Watch how Indianapolis integrates Allen back into the passing attack and whether he faces any snap limitations.
