Cornerbacks Fabian Washington and Lardarius Webb were present and accounted for during Friday's first minicamp workout, but neither participated in drills. Both players are coming off major knee injuries that caused them to miss time in 2009.
"Lardarius and Fabian are doing well," Ravens coach John Harbaugh said. "They are ahead of schedule."
Both wore baseball caps through practice, as did wide receiver Mark Clayton.
Clayton said he had a procedure on his right shoulder three weeks ago to clean it out, and won't be able to participate in workouts for another three weeks.
Harbaugh said Clayton would be available for most of the team's offseason work.
Clayton, a restricted free agent, hasn't signed his tender yet, but he insisted that was a formality. "I just need to go sign it," he said. "I was waiting to get back to Baltimore."
Clayton has been at Oklahoma University finishing up a degree in communications. He will graduate on May 14.
