The Green Bay Packers and the Buffalo Bills both kept their Super Bowl hopes alive with play-off wins.
Packers quarterback Aaron Rodgers threw two touchdown passes – one for Davante Adams and one for Allen Lazard – and ran in for another score, while Aaron Jones also bundled over as the Packers beat the Los Angeles Rams 32-18.
In the later game, touchdowns from Stefon Diggs and Taron Johnson, who produced a 101-yard run to score following an interception, helped the Bills beat the Baltimore Ravens 17-3.
For the Packers it is the second successive year they will play in the NFC Championship game and will face either the Tampa Bay Buccaneers or the New Orleans Saints, who play on Sunday (23:40 GMT).
The Packers have not reached a Super Bowl since they beat the Pittsburgh Steelers 31-25 in Super Bowl XLV 10 years ago and lost 37-20 to the San Francisco 49ers in the championship decider last January.
Meanwhile, the Bills have never won a Super Bowl and will hope to clinch the AFC title for the first time since the 1993 campaign.
Next up for them is the winner of the play-off between the Cleveland Browns and reigning champions the Kansas City Chiefs, with those two meeting at 20:05 GMT on Sunday.
