The Red and Gold waived DE Melvin Oliver on July 15. Oliver was picked by the 49ers in sixth round in 2006 out of LSU. Oliver missed all of last season with a knee injury. In his rookie year in 2006 he played in all 16 games and had 14 starts where racked up 50 tackles with one sack and fumble recovery he ran back for a touchdown against the Oakland Raiders. His release does not impact the depth chart for the 49ers who have a plethora of defense ends including recently signed Justin Smith and the 49ers first round draft pick Kentwan Palmer.
