San Francisco emerged as NFC West champions and the top seeds thanks to Sunday's incredible victory in Seattle.
NINERS DOWN SEAHAWKS IN THRILLER
The Seahawks appeared dead and buried against the 49ers, trailing 26-14 with less than four minutes remaining.
However, the final minutes were unbelievable as the 49ers somehow denied the Seahawks a first-round bye and top spot in the NFC.
Down 26-21 in the final seconds, Seahawks tight end Jacob Hollister charged towards the endzone and fell just inches short of the goal-line on a fourth-down play. It came after a delay of game penalty when Seattle had the ball at the one-yard line.
Dre Greenlaw made the tackle to hold out Hollister with nine seconds remaining as the 49ers earned homefield advantage throughout the postseason after sealing their first division crown since 2012, while the Seahawks will face the Eagles in the wildcard game.
49ers quarterback Jimmy Garoppolo was 18 of 22 for 285 yards and no touchdowns, while Raheem Mostert (two) and Deebo Samuel (one) both rushed for TDs.
Seahawks QB Russell Wilson completed 25 of his 40 throws for 233 yards and two touchdowns.
EAGLES SOAR INTO PLAYOFFS, TITANS JOIN THEM
The Eagles moved through to the wildcard round after capturing the NFC East championship by beating the New York Giants 34-17.
Philadelphia (9-7) finished ahead of rivals the Dallas Cowboys (8-8), who eased past the Washington Redskins 47-16.
Failing to reach the playoffs thrust the future of out-of-contract Cowboys head coach Jason Garrett further into the spotlight but owner and general manager Jerry Jones said: "I'm not going to get into it at all, an evaluation or an assessment. I'm not. I'm going to do exactly what I always do and get up, go forward and do the best job that I can. We'll make those decisions accordingly."
The Titans, meanwhile, used a 35-14 victory against the Houston Texans to advance to the playoffs and set up a wildcard showdown with defending Super Bowl champions the New England Patriots.
The Oakland Raiders missed out on the playoffs following a narrow 16-15 defeat to the Denver Broncos.
RAVENS CAP SEASON WITH 12TH STRAIGHT WIN
Despite the absence of their star starters, the Ravens ended the regular season with another victory, this time against the Steelers.
The Ravens extended their winning streak to 12 as they improved to 14-2 for the season without Lamar Jackson, Mark Ingram, Marshal Yanda and Earl Thomas.
"That puts an exclamation point on an excellent season," said Ravens head coach John Harbaugh.
Pittsburgh required a Tennessee loss to have any chance of becoming only the seventh team since 1970 to reach the playoffs following a 0-3 start.
RAMS SAY GOODBYE TO COLISEUM
The Los Angeles Rams farewelled LA Memorial Coliseum with a 31-24 triumph against the Arizona Cardinals.
As the Rams prepare to relocate to SoFi Stadium in Inglewood, they celebrated one last victory at the historic 96-year-old venue.
"I will miss playing in the Coliseum," said quarterback Jared Goff said. "I'm really excited for SoFi. What Mr. [Stan] Kroenke has done there is going to be something that I don't think the world has ever seen, honestly. It'll be a lot of fun, but I will miss the Coliseum and will miss the history of it, the lighting of the torch, the fireworks, the whole thing. The fanbase we've built here, how much louder it was this year compared to my first year, and just seeing it grow, is really cool."
