Mason  leads the Ravens with 74 receptions for 960 yards and five touchdowns. The 34-year-old two-time Pro Bowl selection is determined to will the Ravens into the playoffs despite the agony of a shoulder that may or may not require offseason surgical repair.

"I'm not going to have surgery just for the sake of having surgery," Mason said. "If it's going to heal on its own, it's going to heal on its own."

Mason has to be cautious off the field, too. Derrick II likes to roughhouse with his dad.

"My son runs up and hits me and wants to do so many things, but I have to tell him that dad's arm hurts," Mason said. "I think he realizes it now, but, at the same time, he's just a boy. I've got to just be careful this Christmas, so my wife will do most of the wrapping, which she does most of every year anyway."

TRAINING ROOM: Offensive tackle Willie Anderson pretty much guaranteed he would play in Sunday's game despite a sprained left ankle suffered against the Cowboys during an awkward fall after being hit from behind.

"I'm going to be there," said Anderson, who returned to play after being carted off the field. "It just hurt like hell. I thought I did something serious the way it was hurting and the way I got hit, but the X-rays and everything was cool. It somewhat limited some things I couldn't do in the game, so I came in just on certain packages."

Cornerback Samari Rolle (sprained foot) and rookie running back Ray Rice (calf contusion) are recovering from injuries and may play this week, too.

L OCK IT UP: Harbaugh predicted that the Patriots will avoid being upset by the Bills.

"New England is going to win a football game, we know that," Harbaugh said. "Everybody knows that. So, we're going out there to win our football game. That's what we need to take care of, and we don't need anybody else to get us in the playoffs. That's our job to take care of that."

Harbaugh won't make any friends in upstate New York with his opinion, but he sounds certain about his prognosticating skills.

"The lock of the week," he said. "Book it."

Meanwhile, Harbaugh said he won't take any special measures to prevent players from following the Patriots-Bills game.

"There are no televisions in the locker room, so I'm sure they'll sneak into the equipment room or whatever and take a look," he said. "You know what? That's OK. Everybody get ready in their own way."

QUICK HITS: Outside linebacker Terrell Suggs was named the Media Good Guy award winner by reporters who regularly cover the Ravens, and free safety Ed Reed was named the team's Most Valuable Player. Suggs was presented a roll of Bounty paper towels in a joking nod to his comments in a radio interview about the Ravens placing bounties on Pittsburgh Steelers running back Rashard Mendenhall and wide receiver Hines Ward. Suggs later backed off those remarks. "This is priceless," Suggs said. "I want to thank all of y'all who voted for me, and for all of y'all who didn't, I'm going to get you. I've been working for this for six years. I saw the names on the wall over there, and I finally got it. I'm going to cry. Y'all let me know if y'all need an interview." ... Suggs said that rookie quarterback Joe Flacco will no longer be referred to as 'Shane Falco' after the quarterback portrayed by actor Keanu Reeves in the movie, "The Replacements." "No more Shane, he performed like a professional last week and everybody was proud of him," Suggs said. "Way to go, Joe. Even I'm wacko for Flacco right now." ... The Jaguars lead the series with Baltimore 9-6, winning the first eight games of the series before losing six in a row from 2000 to 2003 prior to a 30-3 win at home in the teams' last meeting in 2005.
