Jackson did not play against New England after hurting his ankle in a walk-through the previous day, when a Patriots defender stepped on his ankle as they walked through a route.
"I'm going to be out there flying around with my teammates," Jackson said of Monday's game against the Browns.
Jackson participated in full-team work on Monday for the first time since hurting the ankle. He had taken part in individual work only on Saturday and Sunday.
"I felt good, man," he said. "Had a little sore, bruised ankle for the last couple days. So good to be back in the midst of things. Felt good."
Jackson, of course, is a centerpiece of Washington's passing attack. The Redskins signed him shortly after Philadelphia released him in the spring. Jackson's speed is evident in practice and he showed his quickness, as well, catching a touchdown pass with a quick cut back to the middle of the end zone and snagging a pass from quarterback Robert Griffin III.
The Redskins remain upbeat about their passing game, thanks in part to the weapons they've added (including receiver Andre Roberts) and the emergence of tight end Jordan Reed.
"We're going to do some great things," Jackson said.
