Ravens placed ILB Ray Lewis and C Matt Birk on the reserve/retired list. With the transaction, the Ravens save $6.4 million against the 2013 salary cap, which is now officially set at $123 million, according to NFL Network's Ian Rapoport. Birk announced his retirement last Friday, and Lewis made it known that he was retiring prior to the playoffs. Lewis is a sure-fire first-ballot Hall of Famer.
