The Chargers have lost NT Ogemdi Nwagbuo for the season due to a ankle injury.  Nwagbuo played in 12 games for the Chargers this season and he made 19 tackles, 1 tackle for a loss, 1 sack and 2 passes defensed.  The Chargers have signed 30-year old DT Antonio Garay off the practice squad to replace Nwagbuo on the roster.  Garay has not played in the NFL since the 2007 season with the Chicago Bears.  Garay has played in 14 games in his career and he has 12 tackles.  Don’t expect miracles out of Garay.
