KANSAS CITY, Mo. (AP)—The Kansas City Chiefs began practicing Tuesday for their regular-season finale against the Las Vegas Raiders, which could ultimately earn the AFC West champions the No. 1 playoff seed in the conference in an unprecedented situation for the NFL.

Just as the Chiefs were warming up, the league announced that Week 18 games would be played as scheduled, including Kansas City's visit to Las Vegas on Saturday.

But the league also said the Bills-Bengals game from Monday night, which was suspended when Buffalo safety Damar Hamlin went into cardiac arrest, would not be resumed this week.

The Bills, who are 12-3 and beat Kansas City in their head-to-head matchup, needed to beat the Bengals to keep pace with the Chiefs (13-3) for the best record in the AFC, and with it the top seed and lone first-round postseason bye.

Chiefs coach Andy Reid and quarterback Patrick Mahomes were scheduled to speak to reporters Tuesday, but the team pushed back their availability out of respect for Hamlin, who remains in critical condition in a Cincinnati hospital.

They are now scheduled to address reporters on Wednesday.

Mahomes was among many Chiefs players who tweeted they were "praying hard" for Hamlin, who collapsed after making a tackle in the first quarter of Monday night's game. Hamlin was surrounded by team and independent medical staff within seconds, and along with local paramedics, they spent about 20 minutes providing emergency care on the field.

The Bills said that Hamlin's heartbeat was restored before the 24-year-old safety was transferred by ambulance to the University of Cincinnati Medical Center, where he remained sedated in the intensive care unit Tuesday.
