Four teams remain in contention for the Lombardi Trophy, as the Chiefs and Lions joined the top-seeded Ravens and 49ers in the conference championship round with wins on Sunday.
On Saturday, the Ravens and 49ers booked their spots in the conference championship round with wins over the Houston Texans and Green Bay Packers respectively.
Kansas City found a way past Buffalo in frigid western New York just hours after the Detroit Lions battled past the Tampa Bay Buccaneers.
Let's recap this weekend's action from an enthralling Divisional Round.
The Buffalo Bills once again fell short against the Kansas City Chiefs as Sean McDermott's team lost 27-24 at Highmark Stadium on Sunday.
Bills kicker Tyler Bass said the defeat was "totally on me" as he missed a field goal inside the final two minutes to draw the sides level, although the Bills had other opportunities to boost their chances throughout the game.
Bass missed what would have been a game-tying 44-yard field goal, allowing Andy Reid's team to see the game out in Orchard Park.
Reid's team, led by quarterback Patrick Mahomes, ensured they can still defend their NFL Championship crown. After struggling on offense all season, the Chiefs clicked when it mattered most as they ended Buffalo's six-game winning streak.
Mahomes finished the game 17/23 for 215 yards and two touchdowns, picking out tight end Travis Kelce both times.
The pair made NFL history on Sunday as they surpassed Tom Brady and Rob Gronkowski for the most postseason touchdowns as a quarterback-receiver duo.
Bills quarterback Josh Allen rushed for two touchdowns and threw another, but it was in vain as Kansas City progressed, and they are now +350 to win the NFL Championship.
Dan Campbell's Detroit Lions reached the NFC Championship Game for the first time in 32 years as they beat the Tampa Bay Buccaneers 31-23 at Ford Field.
The two teams could not be separated in the first half, with the score locked at 10-10 at halftime.
However, the game came alive in the second half, with the Lions scoring touchdowns on three straight possessions to move into a 31-17 lead in the fourth quarter.
Todd Bowles' team responded when Baker Mayfield picked out Mike Evans with four minutes and 37 seconds left, but they missed their two-point conversion attempt.
Tampa were given one final possession to level the score, but Mayfield was intercepted for the second time in the game, allowing the Lions to celebrate in front of their fans.
Lions quarterback Jared Goff finished with 287 yards and two touchdowns, but despite their impressive performances, they are still considered +700 outsiders for the NFL Championship.
The Lions will face the San Francisco 49ers in the NFL Championship game after Kyle Shanahan's team avoided an upset as they narrowly beat the Green Bay Packers 24-21 on Saturday.
Very few experts gave the Packers much of a chance of winning, but the 49ers needed a late Christian McCaffrey touchdown to seal the deal.
Niners tight end George Kittle scored a second-quarter touchdown to hand his team a 7-6 lead at the break, as both teams struggled to get going on offense due to the driving rain at Levi's Stadium.
Like the other NFC clash, the game burst into life in the third quarter. The Packers stormed into a seven-point lead thanks to Bo Melton and Tucker Kraft touchdowns as well as a successful two-point conversion.
McCaffrey's first of the night came in between those efforts, while kicker Jake Moody fired home a field goal to keep his team within touching distance.
With so much on the line, the 49ers eventually produced a match-winning drive, ending with McCaffrey crashing into the end zone with just over a minute remaining.
The 49ers have set the standard in the NFC for the majority of the campaign, and they are +140 to win the NFL Championship.
Lamar Jackson and the Baltimore Ravens proved too strong for the Houston Texans as they reached their first AFC Championship game since 2012.
The Texans were out to cause a huge upset, with rookie quarterback C.J. Stroud under the spotlight after an incredible first year in the NFL.
Sadly for Houston's fans, they struggled to get into a rhythm, and the Ravens ran out 34-10 winners.
Jackson rushed for over 100 yards and scored two touchdowns of his own, while also throwing touchdown passes to Isaiah Likely and Nelson Agholor.
The Baltimore quarterback looks set to win the MVP award this year and the Ravens will fancy their chances in the AFC Championship game against the Chiefs.
Baltimore will have home advantage and they are +200 to win this year's NFL Championship.
