The Philadelphia Eagles’ NFL playoff seeding is still unsettled, but it could be determined in Week 17.

And there’s one team Birds fans should be rooting against on Sunday — other than the Buffalo Bills, of course.

The Eagles (10-5) will, in all likelihood, be the NFC’s No. 3 seed. Philadelphia just needs to win or tie one of its two remaining games or have the Carolina Panthers lose once to secure that.

The Eagles play the Bills on Sunday, then the Washington Commanders at home in Week 18. The Panthers (8-7) play the Seattle Seahawks and on the road vs. the Tampa Bay Bucs.

The Eagles have no chance at the No. 1 seed. That was cemented when the San Francisco 49ers beat the Indianapolis Colts on Monday night.

The 49ers (11-4) and Seahawks (12-3), who play each other in Week 18, control their own destiny to the No. 1 seed.

The Eagles do, however, have a chance at the No. 2 seed — which would guarantee a second home game at the Linc in the NFC Divisional round.

That path is straightforward. The Eagles need to win their next two games and have the Chicago Bears (11-4) lose their next two.

The Bears are three-point road underdogs against the 49ers on Sunday night, per FanDuel. In Week 18, Chicago hosts the Detroit Lions. The Lions have been eliminated from postseason contention, but it’s likely Dan Campbell would play his starters and try to play spoiler.

If the Eagles secure the No. 2 seed, they could play the Green Bay Packers (9-5-1).

If they’re the No. 3 seed, it’s likely they’ll face either the 49ers or Los Angeles Rams (11-4).

Regardless of seeding, the Eagles will want to go into Buffalo and make a statement by beating the Bills. Philadelphia is a slight 1.5-point road underdog.

And if the Eagles beat the Bills, then Birds fans will be watching “Sunday Night Football” with a real rooting interest as newly-minted 49ers fans.
