Chargers agreed to a five-year extension with P Mike Scifres.

Scifres was set to become a free agent after this season. He's been the Chargers' punter since 2004 and has never missed a game, playing through a hernia injury in 2009. Scifres ranked third in the league last season with a 46.9 yards-per-punt average and the Chargers clearly didn't blame him for their 2010 special teams woes.
