The Ravens signed their second veteran offensive lineman in the past five days, agreeing to a deal with center Tony Wragge.
Wragge, 32, started eight games for the St. Louis Rams last season. He also started 10 games at right guard for the San Francisco 49ers during the 2008 campaign.
Wragge will join former Cincinnati Bengals guard Bobbie Williams, who agreed to a two-year deal with the Ravens last Friday, in providing veteran depth along the offensive line. With Wragge in the fold, the Ravens now have five centers on the roster: starter Matt Birk, rookie Gino Gradkowski, Justin Boren, Cecil Newton and Wragge.
To make room for Wragge on the roster, the Ravens released defensive end/defensive tackle Elliott Henigan, an undrafted free agent out of Alabama-Birmingham.
To make room for Williams, the Ravens have waived defensive end/linebacker Michael McAdoo who tore his Achilles earlier this month during an organized team activity. McAdoo had surgery and is expecting to miss the entire 2012 season.
The Ravens say that McAdoo remains very much in the team's plans, but this is a procedural move because they have to put him through waivers before moving him to injured reserve.
