OWINGS MILLS, Md. — On a day when players were thrilled to return to the Ravens training facility, receiver Derrick Mason faced the sobering possibility of leaving a place he’s called home for the final time. Though it doesn’t become official until Thursday, the 37-year-old wideout will be released in a cap-saving move, along with veterans Todd Heap, Kelly Gregg, and Willis McGahee. Mason was at the facility for his exit physical and met with general manager Ozzie Newsome. After spending the last six seasons in Baltimore, becoming the Ravens’ all-time leading receiver, Mason remains upbeat and willing to return — if the Ravens want him. “If they want me back, I’m back,” Mason said. “That’s all I can say. Now, if some other team wants me, then I think that’s one of those things you have to look at. My first thought would be to come back here. This has been my football home for the last six years, so why leave it so abruptly? I’m going to do what I can, and hopefully they’ll do what they need to do in order to try to bring me back. If not, hey, I can play football.” Mason caught 471
