Indianapolis • NFL sacks champion Robert Mathis admits he made a mistake late last season.
Now it's going to cost him four games and four paychecks.
The Colts' career sacks leader was suspended Friday by the NFL after violating the league's ban on performance-enhancing substances. What exactly Mathis tested positive for remains a mystery but the linebacker said in a statement he was seeking fertility assistance. He acknowledged that he and his wife are expecting a baby.
