Robert Mathis Wednesday publicly addressed his four-game suspension for the first time.

The Colts linebacker will have to sit out the first four games of the season after testing positive for performance enhancing drugs. Last week, he explained in a statement that the substance, Clomid, was found in a fertility medication he was temporarily using. His wife is now pregnant.

Clomid, however, also can be used as a masking agent for performance-enhancing drug treatments. Mathis said that while he asked his doctor if the treatment would violate the NFL's drug policy before he began to take it, he acknowledged that he made the mistake of not also checking with the NFL or the NFL Players Association to determine if the medicine could cause a positive drug test.

"The decisions you make in private can be bad professional decisions," Mathis said Wednesday. "Weigh your options. Of course, I'd like a re-do, but I can't take it back; Just [have to] try to move past it. I've addressed my teammates. They understand my stance and a lot of fans have given great support."

Despite that suspension, Mathis continues to work out with the team this summer.
