While linebacker Brian Orakpo was held out of minicamp on Wednesday, reserve linebacker Rob Jackson had a chance to take reps with the Redskins’ first-team defense.

Jackson did not start last season but played in all 16 games. He said this week’s minicamp was an opportunity for him to show the coaches that he can compete with the first team.

“They’re the starters, but I always have something to prove,” Jackson said. “Every backup at every position has something to prove. You go out there and try to perform and keep the stride going.”

Orakpo had surgery on a torn pectoral musccle in January. He sat out of practice as a precautionary measure.

Drafted by the Redskins in 2008, Jackson has spent the majority of the last two seasons backing up Orakpo as the right outside linebacker. The 26-year-old is fast off the edge, which may help him fit well in the team’s 3-4 system.

In college, Jackson rushed out of the down position, lining up as a defensive end. He said that experience has aided his transition to linebacker.

“I think I fit in real well,” said Jackson. “Going into my third year in this defense, I know where I’m supposed to be. I know where the guys behind me are supposed to be. It’s coming along well.”
