Colts DE Tyquan Lewis (groin) ruled out vs. Steelers

Indianapolis Colts defensive end Tyquan Lewis was downgraded to out with a groin injury for Sunday's game against the host Pittsburgh Steelers.

Lewis, who was listed as questionable heading into the game, was a full participant in practice on both Thursday and Friday.

Lewis, 30, has three sacks and seven tackles in seven games this season.

Also on Saturday, the Colts (7-1) activated Jaylon Jones from injured reserve, signed fellow cornerback Cameron Mitchell to the 53-man roster from the practice squad and waived linebacker Chad Muma and safety Trey Washington.

Jones, 23, was placed on injured reserve Sept. 13 due to a hamstring injury.

Mitchell, 24, recorded three tackles after being elevated to the active roster in each of the last three weeks.
