Williams, an undrafted player out of Maryland, played 23 games for the Ravens in 2011 and 2012. He only totaled four catches, but he made his mark with nine tackles on special teams.
The Ravens placed Williams on injured reserve with a hamstring injury in the final week of the 2012 regular season. Williams was then released before the start of the 2013 regular season after suffering hamstring and shoulder injuries.
He signed with the New England Patriots in November 2013 but only lasted 10 days with the team.
The Ravens are set with their top four wide receivers this season: Torrey Smith, Steve Smith, Marlon Brown and Jacoby Jones. Williams would need to make contributions on special teams in order to make the Ravens as their No. 5 or No. 6 receiver.
