The Ravens may lose two of their leaders this offseason. Safety Ed Reed said Saturday that he's "50-50" on whether he will retire and wide receiver Derrick Mason also said he'll consider ending his career. Reed has been dealing with a serious neck injury the past few seasons. "It's 50-50," Reed said. "I got great doctors that I deal with. So I'm going to re-evaluate things and see how it goes. ... At the end of the day, it's my decision to play with injuries going forward for my career." Mason, 36, completed the final year of his contract with Baltimore and will become a free agent in March.
