Alex Marvez says the following in his blog:
Wide receiver Ted Ginn Jr. participated in drills without a red injury jersey at the start of today's minicamp practice. Ginn, the team's first-round draft choice, was unable to participate in last month's rookie minicamp while recovering from a sprained foot.
That's very good news. Of course, mini-camps are supposed to be non-contact, but it's a positive sign nonetheless.
More mini-camp updates coming as they roll in.
