"I always had a great deal of respect for Darrell as a player in the NFL," said San Francisco head coach Mike Nolan. "I appreciated his dedication and work ethic during his season with the 49ers. He always had a positive attitude every day he came to work. While we are going in a different direction, I know he can still produce and be an asset to an NFL team this year."
