Allen (groin) is practicing Wednesday, James Boyd of The Athletic reports.
After missing last Sunday's game against Washington, Allen's return to practice puts him on track to play Week 5 against the Steelers. With Alec Pierce (heel) still on injured reserve, the Colts need all the help they can get at the position after Laquon Treadwell and Ashton Dulin were forced into heavy snaps alongside Josh Downs against the Commanders.
