Chicago Bears have secured an NFL play-off spot for the first time since 2010 after they beat the Green Bay Packers 24-17 to clinch the NFC North title.
The Bears (10-4) have won seven of their past eight games and Sunday's victory means they are no longer tied with the New York Jets for the third-longest active post-season drought.
They finished last in the division in each of the past four seasons but quarterback Mitchell Trubisky helped lead two fourth-quarter scoring drives on the way to victory.
Eddie Jackson ended Packers star Aaron Rodgers' NFL-record streak without an interception at 402.
Pittsburgh Steelers halted a last-minute drive from the New England Patriots to win 17-10 and end a three-game slide.
The playoff-chasing Steelers had experienced a mid-season slump and their grip on the AFC North had slipped as the Baltimore Ravens (8-6) drew ever closer to the top spot with a 20-12 win over the Tampa Bay Buccaneers.
Pittsburgh quarterback Ben Roethlisberger threw what turned out to be the game-winning touchdown in the second quarter, connecting with Antonio Brown for a 17-yard score.
But it was the Steelers' defence which came up big, picking off Tom Brady with eight minutes left to play in the redzone and forcing a turnover with 14 seconds left to play.
The Steelers improve to 8-5-1 while the Patriots maintain top spot in the AFC East with a 9-5 record.
Indianapolis Colts beat the Dallas Cowboys 23-0 while the Atlanta Falcons cruised past the Arizona Cardinals 40-14
Miami Dolphins lost 41-17 at the Minnesota Vikings and the Tennessee Titans beat the New York Giants 17-0.
Washington Redskins won 16-13 at the Jacksonville Jaguars and the Denver Broncos lost 17-16 to the visiting Cleveland Browns.
Buffalo Bills triumphed 14-13 over the Detroit Lions and the Cincinnati Bengals beat the Oakland Raiders 30-16.
