FOXBORO -- If Tom Brady plays this Sunday, it will be with a sprained left shoulder, according to a tweet from the NFL Network's Albert Breer late Friday afternoon. Breer, quoting a source with direct knowledge of the injury, said the injury to the shoulder sustained in the Christmas Eve win over the Dolphins is "not an instability problem," indicating Brady would be able to play with the injury. 

FOXBORO -- Tom Brady was again limited at practice on Friday with a left shoulder injury but is officially listed by the team on its injury report as "probable" for the regular season finale Sunday against the Bills at Gillette Stadium. Probable is clarified on the NFL participation report as "virtual certainty the player will be available for normal duty." The only two players to miss practice all week, Logan Mankins (left knee) and Sebastian Vollmer (right foot/back) were the only two players ruled out.

Patriots tackle Matt Light joined The Big Show Friday, saying that he hopes to play Sunday's regular-season finale after missing last Saturday's game with an ankle injury.

"Like always, I'm going out there and doing everything I can to get and be able to be on the field," Light said. "We'll see how it goes. "It's always difficulty when you're rehabbing something or trying to come back from something, but we've had a good week this week, and I'm pretty excited about this weekend."

Peter King of Sports Illustrated and NBC Sports joined the Mut & Merloni show Friday with guest hosts Kirk Minihane and Rob Bradford to talk about news from around the NFL.

Patriots quarterback Tom Brady has a left shoulder issue, but there have been varying reports about the extent of the injury.

"I'm sure it's something," King said. "But I doubt sincerely it's something remotely serious that will either threaten his ability to play in this game or to succeed in the game."

FOXBORO -- Tom Brady was on hand Friday for the start of practice for a second straight day after being listed on Thursday's injury report as limited with a left shoulder ailment. 

The team practiced in sweats and shells inside Gillette Stadium with only Logan Mankins (left knee) and Sebastian Vollmer (foot/back) missing practice for a third straight day. 

The team will hold their weekly pregame walkthrough on Saturday before hosting the Bills Sunday at Gillette in the regular season finale at 1 p.m. ET. 

FOXBORO -- Patriots coach Bill Belichick was pressed several times at the beginning and end of his Friday news conference about the health of Tom Brady. He would not elaborate on his health and did not mentioned the injured left shoulder.

At the beginning, Belichick was asked what Brady was able to do on Thursday, after being given Wednesday off for "non injury related" issues.

"Play quarterback," Belichick answered. 

With the postseason looming, the Patriots have to feel good about two stats that have continued to show improvement over the second half of the regular season -- the dip in the amount of penalties they’ve taken, as well as the decrease in the number of turnovers they’ve committed.

Patriots offensive coordinator Bill O’Brien has emerged as a head coaching candidate, and is “expected to receive overtures to interview with teams,” according to Jason LaCanfora of the NFL Network.
