According to Mike Florio of ProFootballTalk.com, Atlanta Falcons center Jeremy Newberry is retiring.
Citing a league source, Florio reports that Newberry was having trouble with a knee that required microfracture surgery several years ago.
A two-time Pro Bowler (2001, 2002), Newberry started 107 games during an 11-year career that began with him being chosen with the 58th overall pick of the 1998 NFL Draft by the San Francisco 49ers. After nine seasons with the 49ers, Newberry spent the 2007 season with the Oakland Raiders before starting three games for the 2008 San Diego Chargers.
Atlanta signed Newberry on June 15, and he was expected to compete with fellow free agent signee Brett Romberg for the top back-up job behind starter Todd McClure.
Center Alex Stepanovich, who was released when the team signed Newberry, is available and could be re-signed for training camp.
