Indianapolis Colts linebacker Shaquille Leonard is officially ruled out of the team's Thursday night contest with a concussion and broken nose, according to Joel Erickson of the Indianapolis Star.
Leonard missed the first three games of the season after undergoing offseason back surgery. The three-time All-Pro linebacker played just 16 snaps on Sunday before exiting with concussion-like symptoms. Prior to this season, Leonard had missed seven games across his first four years in the league.
The Colts could certainly use Leonard's help on defense. Indianapolis is currently tied for third-fewest with seven total sacks and rank tenth in adjusted sack rate.
