Ravens player to watch

S Ar’Darius Washington. He’s been a big part of Baltimore’s defensive improvement down the stretch this season, but the secondary did allow a couple of lengthy touchdown throws by the Steelers last weekend and now faces an even bigger challenge against Buffalo’s passing game.

Bills player to watch

QB Josh Allen. Though the seventh-year starter is 1-3 in divisional playoff appearances, he’s combined for 975 yards passing and six touchdowns with one interception, and 159 yards rushing and three scores in those outings. With two TDs passing last weekend, Allen increased his postseason total to 23 to break Hall of Famer Jim Kelly’s franchise record (21). In the regular season, Allen topped the 40-TD total for a fifth straight year with 28 touchdowns passing, 12 rushing and one receiving, while throwing a career-low six interceptions.

Key matchup

All four players are scheduled to play Sunday.
