Pittsburgh won the AFC North in spectacular fashion Sunday, scoring the winning touchdown with 9 seconds remaining to beat archrival Baltimore 31-27.

Antonio Brown reached over the goal line after taking in a short pass from Ben Roethlisberger for the 4-yard score. Brown was standing up inside the 1, but somehow extended the ball — barely — into the end zone.

The Steelers (10-5) scored 21 points in the fourth quarter. They eliminated the Ravens (8- 7) from contention.

Defending Super Bowl champion Denver was knocked out, too, with its loss at Kansas City. The Broncos have lost three in a row and five of seven.

The entire AFC playoff field is set: New England, Oakland, Kansas City, Pittsburgh, Houston and Miami.

The Steelers will be the No. 3 seed in the AFC and host the No. 6 seed during wild-card weekend on either Jan. 7 or 8. Pittsburgh earned the third spot over Houston based on the strength-of-victory tiebreaker, heady territory considering it was 4-5 after falling to Dallas on Nov. 13. As New Year’s nears, the Steelers haven’t lost again.

Kansas City secured a playoff spot when the Ravens lost, and can still win the AFC West.

Earlier this weekend, Atlanta beat Carolina 33-16 , then the Falcons clinched the NFC South title when New Orleans beat Tampa Bay 31-24. The Bucs’ loss also allowed the New York Giants, losers to Philadelphia on Thursday night, to clinch a wild-card spot. Atlanta now has a chance in its regular-season finale to clinch a first-round bye after Seattle lost 34-31 to Arizona.

Houston beat Cincinnati on Saturday night to clinch its second straight AFC South title after Tennessee’s 38-17 loss to Jacksonville . The Texans also will host a wild-card game.

Green Bay won its fifth straight to move closer to the NFC North title, eliminating Minnesota with a 38-25 victory. The Packers moved into the lead for a wild-card berth, and now the Packers must wait to face Detroit for the division crown on Jan. 1. The Lions lost to the Cowboys on Monday, so both the Packers and Detroit enter Sunday night’s contest with matching 9-6 records.

Miami beat Buffalo 34-31 in overtime to move closer to its first playoff berth since 2008. The Dolphins clinched an AFC wild-card berth Sunday night when Denver lost to Kansas City 33-10.

The Redskins (8-6-1) routed Chicago 41-21 to keep them alive a bit longer in the NFC.
