The Broncos signed defensive end Derek Wolfe to a four-year contract extension on Friday.

The Denver Broncos have signed defensive end Derek Wolfe to a four-year contract extension, the team announced Friday.

Wolfe had a breakout season for the Broncos this year, posting 5.5 sacks and 49 combined tackles in 12 games.

The 25-year-old was suspended in July for the first four games of the season for violating the NFL’s policy on performance-enhancing drugs.

Wolfe starred at the University of Cincinnati from 2008–11, and was selected in the second round of the 2012 NFL draft by the Broncos.

In four NFL seasons, Wolfe has delivered 17 sacks and 140 combined tackles.

The Broncos host the Pittsburgh Steelers on Sunday at Mile High Stadium in the divisional round of the NFL playoffs.
