Campbell was given permission to explore a trade after Donovan McNabb was acquired from Philadelphia last week. Campbell couldn't find a team that would make a suitable offer to him as a restricted free agent, so he signed the tender Monday.
The move puts the onus back on the Redskins to find a trade partner for Campbell. Their best chance might come during next week's draft.
Campbell has stopped attending voluntary workouts at Redskins Park and is not expected to attend this weekend's three-day voluntary minicamp. Campbell doesn't want to be a distraction to McNabb, sources familiar with the situation told Redskins Insider.
Head coach Mike Shanahan is fine with Campbell staying away this weekend, the sources said, but if he is still with the team in early May, he will be expected to attend the voluntary camp May 7-9.
The Redskins also signed free agent nose tackle Anthony Bryant, who spent last year on the New York Giants practice squad.
