The Steelers can clinch their first AFC North title since 2017 with a win and Cleveland losing. They can also clinch their first playoff berth in three years with a combination of a win or a Tennessee loss, a Las Vegas loss or tie or a Miami loss or tie. ... Due to COVID-19 rescheduling issues, the Steelers are closing a stretch of playing three games in 12 days, which began with 19-14 win over Baltimore on Dec. 2. ... Pittsburgh is 29-24 on Sunday nights, and 1-4 in its past five after ending a nine-game winning streak. ... The Steelers were the NFL’s 12th team to win their first 11 games. ...

RB James Conner is expected to play after missing the past two games on the reserve/COVID-19 list. Minus Connor, the Steelers managed just 21 yards on 14 carries, the franchise’s lowest single-game rushing total since 1970. ... With a league-leading 44 sacks, Pittsburgh has at least two in each game this season. The Steelers also have a sack in 69 consecutive games, dating to Week 9 of the 2016 season, in matching the NFL’s longest streak set by Tampa Bay (1999-2003). ... LB T.J. Watt leads the league with 12 sacks and is one shy of becoming just the sixth player with 13 or more in three straight seasons. ... The Bills' win at Pittsburgh last year clinched their second playoff berth in three years. ...

WR Stefon Diggs is tied with Chargers’ Keenan Allen for the league lead with 90 catches — 10 short of matching Buffalo’s single-season record set by Eric Moulds in 2002. Diggs' 1,037 yards receiving rank fifth in the league. ... With two interceptions against the 49ers, Buffalo has forced 12 takeaways (eight interceptions) in its past six outings. ... CB Tre’Davious White’s fourth-quarter interception last week was his 16th second-half career takeaway. ... Fantasy tip: With White expected to shadow WR JuJu Smith-Schuster, rookie Chase Claypool could draw Levi Wallace, who struggled in allowing 49ers WR Brandon Aiyuk to make five catches for 95 yards and a touchdown.
