The Indianapolis Colts will once again be without star linebacker Shaquille Leonard.
Leonard missed the first three games of the season due to offseason back surgery. The linebacker played just 16 snaps, earning two tackles, in Sunday's loss before exiting with the concussion.
With the quick turnaround before Thursday Night Football, the Colts will not take any chances with the head injury.
In addition, Reich ruled out defensive tackle Tyquan Lewis, who is also dealing with a concussion.
As for running back Jonathan Taylor, who is dealing with an ankle injury, Reich said the team would see how he responds in the coming days.
NFL Network Insider Ian Rapoport reported Monday that scans on Taylor's ankle came back clean, but the team will continue to monitor given the short week. Pelissero added that Talylor is dealing with mild turf toe in addition to his ankle issues.
