Derek Wolfe 'Disappointed In Himself' Over Suspension

ENGLEWOOD, Colo. (CBS4) - Derek Wolfe is practicing with his teammates at training camp even though he won't be for the team's first four regular season games.

Wolfe was suspended for violating the league's permformance enhancing drug policy.

On Friday, the first day of camp, he declined to say what he took that caused the positive test.

"We're not going to talk about that right now," he told reporters. "It was personal issues I was dealing with, and I dealt with it in a manner that I shouldn't have. I'm just going to move past it. I just want to talk about football."

Wolfe's absence will likely mean more playing time for Malik Jackson, although Jackson suffered a minor injury during practice Friday.

"I'm disappointed in myself. I let the fans down, I let my teammates down, my coaches and the whole organization," Wolfe said. "At the end of the day, I'm going to sit out four games and I'm going to come back strong."
