The Bills host the seventh seed Pittsburgh Steelers on Sunday, while Miami travel to the Kansas City Chiefs for a clash with the AFC West champion following the latter's 13-12 win over the Los Angeles Chargers.
The Tampa Bay Buccaneers showed they can still challenge in the post-Tom Brady era by clinching their third consecutive NFC South title with a 9-0 win over Carolina Panthers.
It is the fourth time in a row that they have qualified for the play-offs but the first without Brady, their superstar quarterback replaced by Baker Mayfield.
Mayfield was struggling with a rib injury but still contributed to the drives that enabled Chase McLaughlin to kick three field goals.
The Buccaneers finished the season with a 9-8 record – the same as New Orleans Saints but progress ahead of their rivals due to their higher win percentage in common games.
Tampa Bay meet the Philadelphia Eagles in the first week of the play-offs after the Eagles continued their late-season free-fall with a 27-10 loss to the New York Giants.
The New Orleans Saints defeated the Atlanta Falcons 48-17 but the result in North Carolina meant their win was not enough to advance.
The Jacksonville Jaguars' 28-20 loss to the Tennessee Titans saw the Houston Texans take the AFC South title.
Devin Singletary produced the key touchdown for the Texans in the final quarter of their 23-19 victory over the Indianapolis Colts with quarterback CJ Stroud passing for 264 yards and scoring two touchdowns.
The Texans will face the Cleveland Browns in the super wild card round, with the Browns losing 31-14 to the Cincinnati Bengals after fielding a large number of back-up players.

The Detroit Lions may be without breakout tight end Sam LaPorta for their first home play-off game in 30 years after the rookie left the field with a knee injury in the middle of Detroit’s 30-20 win over the Minnesota Vikings.
The Lions will meet former Detroit quarterback Matthew Stafford next week after he led the Los Angeles Rams over the San Francisco 49ers 21-20.
Dak Prescott continued his stellar season, lifting the Dallas Cowboys to the NFC East title with a 38-10 victory over the Washington Commanders.
A 17-9 win over the Chicago Bears was enough for the Green Bay Packers to secure a play-off berth and knock the Seattle Seahawks out of post-season contention, despite the Seahawks beating the Arizona Cardinals 21-20.
Elsewhere, the Las Vegas Raiders ended their season with a 24-17 win over the Denver Broncos, while the New York Jets beat the New England Patriots 17-3 in what may have been Bill Belichick's last game in charge.
