INDIANAPOLIS --- Colts inside linebacker D’Qwell Jackson leads the NFL in tackles, and he’s also the leader when it comes to making sure the back-up inside linebackers are ready for Sunday, with Nate Irving now on Injured Reserve with a wrist injury and fellow starter Jerrell Freeman still out of practice with hamstring and ribs injuries. Jackson himself did not practice Wednesday with a quad injury before practicing on a limited basis Thursday.
The candidates for increased playing time include Sio Moore, Josh McNary, and Amarlo Herrera, the Colts 6th-round pick out of Georgia who was elevated from the practice squad this week.
