FOX19 - Former University of Cincinnati standout Derek Wolfe has been suspended four-games by the NFL for violation of the league's substance abuse policy.
The defensive end can remain with the Denver Broncos throughout training camp and preseason, but will begin serving his suspension on Sept. 5 and will not be eligible to return until Monday, Oct. 5.
Wolfe finished fourth on the Bearcats' all-time list with 19.5 sacks and was named the Big East Conference Co-Defensive Player of the Year his senior season.
He was selected by the Broncos in the second round, 36th overall, of 2012 NFL Draft.
"During the offseason I took a medication which is on the banned substance list," Wolfe said in a statement on Friday. "The medication is not a substance which would enhance my on-field performance in any way and I genuinely was unaware that it was prohibited, but players are responsible for what is in their bodies."
