The Washington Redskins activated long snapper Nick Sundberg from injured reserve and announced offensive tackle Jammal Brown has been cleared to practice. Sundberg was placed on injured reserve with the designated to return label after finishing the season opener with a broken arm. Justin Snow, who has handled the long snapping duties since Week 2, was released after appearing in his 200th career game last week. Brown has yet to play in 2012 after aggravating a hip injury over the offseason. Cornerback David Jones, who was signed Sept. 25, was waived and replaced by practice squad cornerback Domonique "D.J." Johnson.
