Final week of the NFL's regular season arrives with No. 1 seeds still undecided in AFC and NFC

The NFL's regular season has reached its final weekend with plenty undecided in terms of the playoff picture, including the No. 1 seed in both the AFC and NFC.

Here's what to watch over the next few days:

The Denver Broncos, New England Patriots and Jacksonville Jaguars all have a shot at the No. 1 seed in the AFC, which includes a first-round bye and home-field advantage through the playoffs.

The Broncos (13-3) have the clearest path — if they beat the Los Angeles Chargers (11-5) on Sunday, they'll earn the top seed. They could also sneak into the top spot depending on the results for the Patriots and Jaguars.

The easiest way for the Patriots (13-3) to earn the top spot is to beat the Miami Dolphins (7-9) on Sunday and hope the Broncos lose to the Chargers. There are also a few unlikely scenarios — including ties in Week 18 — where they could clinch.

The only way the Jaguars (12-4) will be the No. 1 seed is if they beat the Tennessee Titans (3-13) on Sunday and the Broncos and Patriots both lose. Jacksonville can also clinch the AFC South with a win.

The Houston Texans (11-5) are still in the mix for the AFC South title if they can beat the Indianapolis Colts (8-8) and the Jaguars lose.

The Baltimore Ravens (8-8) and Pittsburgh Steelers (9-7) are fighting for the AFC North title and the final AFC playoff spot on Sunday. The Steelers need to win or tie while the Ravens have to win.

The Seattle Seahawks (13-3) face the San Francisco 49ers (12-4) on Saturday night with the NFC's No. 1 seed, first-round bye and home-field advantage on the line. The Seahawks have to win or tie while the 49ers must win.

The Carolina Panthers (8-8) face the Tampa Bay Buccaneers (7-9) on Saturday for the NFC South title and final NFC playoff spot. Carolina's easiest path is to beat or tie the Bucs, but the Panthers could also sneak into the playoff field if they lose and the Atlanta Falcons (7-9) beat the New Orleans Saints (6-11).

Tampa Bay must beat Carolina and then hope the Falcons lose or tie.

LONDON (AP) — Darts phenom Luke Littler will bid for a second straight world title after reaching his third final in a row on Friday.

The 18-year-old Littler beat Ryan Searle 6-1 in the semifinals at Alexandra Palace and will try to become the first player to win back-to-back titles since Gary Anderson a decade ago.

Anderson could have been Littler's opponent in Saturday's final but lost 6-3 to Gian van Veen, a 23-year-old Dutchman who won the Youth World Championship in November.

Whoever wins will claim a record prize of 1 million pounds ($1.35 million).

“It’s a massive prize, but it’s the trophy on the stage, it’s not the money,” Littler said, “... so hopefully I can lift the trophy again and think about the money after.

“It feels great, not many people have done it, the first three world championships reaching the final. I have joined a short list of people doing that. Now obviously the only goal is to join the list of people going back-to-back champions.”

Littler reached the final in 2024 at the age of 16, losing to Luke Humphries, but beat Michael van Gerwen in last year's final.

Van Veen has followed in the footsteps of countrymen Raymond van Barneveld and Van Gerwen in getting to the final.
