Browns restricted free-agent linebacker D'Qwell Jackson will sit out the team's mandatory minicamp June 10-12 and is uncertain about training camp. Jackson told the Cleveland Plain Dealer of his plans, despite being medically cleared to play. "I still want to retire as a Cleveland Brown, but I have to be protected," Jackson said. "Unfortunately, this is the business side of it and I have to do what I have to do. But on Sundays, I'll still be the same player I've been for the last four years."
