The Redskins tweeted a photo of their biggest offseason acquisition working out in the weight room Monday, and the three-time Pro Bowl receiver tweeted a photo of his No. 11 jersey in his locker.
Jackson wore No. 10 with the Philadelphia Eagles and had said he would try to see if franchise player Robert Griffin III - the Redskins' current No. 10 - would be willing to switch. Griffin quickly nixed the idea.
Jackson signed with Washington on April 2, less than a week after getting released by the Eagles. The Redskins started their workouts the following week, but Jackson went ahead with his vacation.
