Robert Mathis tears Achilles; Colts lose him for year

One of the best pass-rushers over the past decade has been Indianapolis Colts defensive end/outside linebacker Robert Mathis, who led the NFL with 19.5 sacks in 2013.

Many regard him as the best player on the Colts roster not named Andrew Luck, but they'll have to do without Mathis for the 2014 season.

Mathis has already been suspended for the first four games for violating the NFL's Performance Enhancing Drug policy. This injury will likely keep hi out for all of 2014.

Mathis has registered 69 sacks over the past six seasons, and he's amassed 111 over his 11-year NFL career.
