Jarvis Jenkins’s four-game suspension has ended (John McDonnell/The Washington Post)

Linebacker Rob Jackson and defensive end Jarvis Jenkins were on the practice field Tuesday with the Washington Redskins. Their four-game suspensions for violations of the league’s drug policies have expired.

“Today I didn’t feel rusty at all,” Jackson said following Tuesday’s practice. “It was pretty simple. We ran the base plays. So I just reacted and I felt like I didn’t miss a beat today.”

Jackson was suspended for violating the NFL’s substance abuse policy. Under the terms of that policy, he was able to be at the team’s training facility during his suspension. That wasn’t the case for Jenkins, who was suspended for a violation of the sport’s policy on banned performance-enhancing substances. Jenkins had to be away from the team.

“I really didn’t feel disconnected,” Jenkins said. “Even though I wasn’t here, my [fellow defensive] linemen still texted me. I was still texting a lot of guys. …I was a little out of the loop because I wasn’t there. But the communication was still there.”

The Redskins were granted one-week roster exemptions for Jackson and Jenkins. Even so, the team acknowledged Tuesday that it released place kicker John Potter and defensive end Phillip Merling. Potter had filled in for injured place kicker Kai Forbath for three games.

This was the Redskins’ final practice of their bye week. Players are off until Monday. The team next plays Oct. 13 at Dallas.
