ENGLEWOOD, Colo. (AP) Denver Broncos defensive end Derek Wolfe will miss the first month of the season after being suspended by the NFL for violating the league's policy on performance enhancing substances.

Wolfe said in a statement he took medicine this offseason that he didn't realize was prohibited by the NFL. He apologized to the Broncos and their fans.

Wolfe played in every game last year, contributing to a Denver defensive line that allowed 79.8 rushing yards per game, the lowest single-season figure in team history.

He was a shell of himself, however, after missing a good chunk of the 2013 season, which was marked by a seizure on the team bus. Doctors believe that was related to a bruised spinal cord he suffered that preseason.
