Antonio Brown has been ruled out of the Pittsburgh Steelers' game against the Denver Broncos with a concussion.

Sources said Brown told people in the building he was optimistic he could return, but that was hardly a guarantee considering the sensitive nature of concussions. 

Brown has consulted an NFL-approved, offsite neurologist daily.

ESPN's Bob Holtzman reported earlier in the week that things were "not looking good" for Brown, who took a vicious hit from Bengals linebacker Vontaze Burfict in the final minute of the Steelers' 18-16 wild-card win.

Mike Tomlin rejected a rumor that Joey Porter received a game ball after the Pittsburgh Steelers' win over the Cincinnati Bengals.

Porter was exchanging words with Bengals players when Adam “Pacman” Jones was flagged for a personal foul that set up the winning field goal.

Paul Guenther, defensive coordinator of the Bengals, called Porter “an embarrassment to the coaching profession,” while longtime Bengals tackle Andrew Whitworth said he respects Tomlin and the Steelers but doesn’t have any respect for Porter.

“No class,” Whitworth said.

Ben Roethlisberger said that he sprained his AC joint and tore some ligaments in his shoulder in the second half against the Cincinnati Bengals after he was sacked by Vontaze Burfict.

“It didn’t hurt when I reached back to throw,” Roethlisberger said of his late-game drive. “But it was pushing forward to throw and then the end of the throw. So I definitely felt like I was shortening up my motion up a little bit, which is why we threw some screens, and couldn’t really get the ball down the field… I think it just more affected how I could throw it.”

Roethlisberger is still trying to work his way back from the injury.

“It’s definitely sore,” Roethlisberger said. “I think it’s a little bit better than it was, but we’re still going to just take it day-by-day.”

Roethlisberger is expected to play against the Denver Broncos in the Divisional Round.

While Ben Roethlisberger is likely to play in the Pittsburgh Steelers' playoff game on Sunday at the Denver Broncos, Antonio Brown's situation is "not looking good."

The Steelers believe Roethlisberger suffered a sprained AC joint in his right shoulder.

Brown is in the concussion protocol after taking a hit from Vontaze Burfict during the Steelers' game-winning drive.

DeAngelo Williams has been ruled out of the Pittsburgh Steelers' playoff game against the Cincinnati Bengals.

Williams filled in nearly seamlessly for Le'Veon Bell this season. The veteran back finished with 907 yards on 200 totes and 11 rushing touchdowns.

Fitzgerald Toussaint is expected to get the start with Jordan Todman seeing snaps as a backup.

The Seattle Seahawks finished the 2015 season ranked first in Football Outsiders' Total DVOA following their blowout victory of the Arizona Cardinals.

The Seahawks have now finished first in DVOA for four straight seasons, which is the first time the feat has been accomplished.

The Cincinnati Bengals rank second in Total DVOA ahead of the Cardinals, Carolina Panthers and Kansas City Chiefs.

These were also the five teams, the Seahawks, Bengals, Cardinals, Panthers and Chiefs, to finish the 2015 regular season in the top-10 in both Offensive and Defensive DVOA.

The NFL has announced its television schedule for the 2015 playoffs.
