The San Francisco 49ers announced Tuesday that DE Melvin Oliver has been waived.
Oliver originally joined the 49ers as a sixth-round draft pick out of LSU in 2006. As a rookie, he played in 16 games with 14 starting assignments and finished with 50 total tackles, one sack and a fumble recovery that he returned for a touchdown. Oliver missed the 2007 season after suffering a knee injury during organized team activities in June.
