Mathis (Achilles) signed a one-year extension with the Colts on Tuesday, ESPN reports.

Analysis:

Mathis' new contract with the Colts extends through the 2016 season. Although his four-game suspension has now been completed, Mathis remains on injured reserve after suffering a torn Achilles while working out earlier this month. As a result, Mathis, who led the NFL with 19.5 sacks last season, won't be available until the 2015 campaign.
