The Pittsburgh Steelers and Denver Broncos will face off for the second time this season in Sunday's divisional-round matchup.
The Steelers came out on top in Week 15, winning a shootout 34-27. However, both teams look distinctly different entering this contest.
Here are three things you need to know:
No Brown, Williams for Steelers
If Pittsburgh is to win, they'll have to do it without two of their best offensive players.
Wide receiver Antonio Brown was ruled out after suffering a concussion against the Cincinnati Bengals, while running back DeAngelo Williams remains sidelined due to a foot injury.
The entire offense will now rely on the injured arm of Ben Roethlisberger, and with Denver's top-ranked defense tasked with stopping him, it could be too much to overcome for Roethlisberger and co.
Will, or can, either QB throw deep?
The game will likely be scrappy, and won't feature some of the spectacular passing plays we've come to expect from both teams.
Peyton Manning has played less than two quarters of football since Nov. 15, and the team admitted he won't be fully healthy until the offseason due to a torn plantar fascia. Even before the injury, what little arm strength the future Hall of Famer once possessed appeared to be gone. It's unlikely Denver will ask him to attempt more than one or two downfield shots.
Roethlisberger suffered an AC joint sprain and torn ligaments in his right shoulder in last week's victory over the Bengals. He reentered the game for the final drive, but was clearly limited to just underneath throws. A week of rest may have helped, but it's unlikely he'll be as effective as normal.
Denver wants revenge
During their last meeting, Steelers center Cody Wallace launched himself into Broncos linebacker David Bruton after the whistle, and was subsequently fined $23,152.
Denver players were vocal in their displeasure of the hit, and may look to retaliate Sunday.
Broncos safety Darian Stewart said he'll be "cutting" Wallace if he gets the opportunity, and while Pittsburgh players were quick to brush aside his comments, the Steelers could find themselves in a heated contest for the second week in a row.
