One key thing to know about every NFL Week 18 game

In Cleveland, where the Browns have secured the AFC’s fifth seed, Joe Flacco will rest his nearly 39-year-old bones, giving way to Jeff Driskel as the Browns become the sixth team in NFL history to start five quarterbacks in a season and join the 1984 Bears as the only teams to qualify for the postseason with five different starters at quarterback. (Three teams did so during the 1987 strike season.)

Here’s a look at some other interesting facts entering Week 18.

Steelers (9-7) at Ravens (13-3), 4:30 p.m., ABC, ESPN, ESPN Plus, ESPN Deportes: Baltimore has cut a swath of destruction against some of the NFL’s best teams, going 4-1 against 11- and 12-win teams and averaging a 27-point margin of victory in those wins. One of its three losses was to Pittsburgh by seven points in October.

NFL Week 18 playoff scenarios: A record 20 teams still in contention

Texans (9-7) at Colts (9-7), 8:15 p.m., ABC, ESPN, ESPN Plus, ESPN Deportes: Rookie C.J. Stroud has averaged 274.6 passing yards per game and has had six games of 300 or more yards (with 20 touchdowns and five interceptions).

Buccaneers (8-8) at Panthers (2-14), 1 p.m. Fox: Tampa Bay quarterback Baker Mayfield turned out to be a $4 million bargain as a starter after being used for temp duty by the Panthers and Rams last season. He is 12th in the league in passing yards (3,598) and a big reason Tampa Bay is trying to win a third consecutive NFC South division title.

Browns (11-5) at Bengals (8-8), 1 p.m., CBS: Locked into the AFC’s No. 5 seed, the Browns must decide how many of and for how long their other starters will play ahead of wild-card weekend.

Vikings (7-9) at Lions (11-5), 1 p.m., Fox: Green Bay put up 470 total yards and 33 points against Minnesota, which allowed 30 or more points for the second straight week. The Vikings also had zero sacks, the first time this season they had been shut out in that category.

Jets (6-10) at Patriots (4-12), 1 p.m., Fox: In six of the weekend’s 16 games, teams have little beyond pride on the line, but this matchup is intriguing because of Bill Belichick’s future, not that he’s giving any clues. If he were to do that, he’d “put it out there on Twitter and MyFace,” he joked.

Falcons (7-9) at Saints (8-8), 1 p.m., CBS: Derek Carr has thrown two or more touchdown passes in four consecutive games, the longest streak by a Saints quarterback since Drew Brees’s five games in 2019-20. He has completed 10 of 13 passes on third down for 95 yards and a touchdown.

Jaguars (9-7) at Titans (5-11), 1 p.m., CBS: Jacksonville linebacker Josh Allen is having his first double-digit sack season (fifth in the league with 13½) since he was a rookie in 2019. He also has 55 tackles, 27 pressures, two forced fumbles and an interception.

Seahawks (8-8) at Cardinals (4-12), 4:25 p.m., Fox: Arizona has gained some clarity for its draft plans, at least as far as Coach Jonathan Gannon is concerned. He declared Kyler Murray “our franchise quarterback” with the team 3-4 since Murray returned from injury.

Bears (7-9) at Packers (8-8), 4:25 p.m., CBS: Green Bay, which needs only a victory to qualify for the playoffs, must get it against a division rival that, while eliminated from playoff contention, has won five of its past seven games behind Justin Fields and owns a defense that has been dominant since the arrival of Montez Sweat in a trade. It’s good to be the Bears, who hold the top pick in the NFL draft.

Chiefs (10-6) at Chargers (5-11), 4:25 p.m., CBS: After leading the NFL in total yards and scoring last season, Kansas City’s offense continues to sputter. Against Cincinnati, it scored on seven drives, but only one resulted in anything more significant than a field goal. Defense remains the team’s strength, ranking second in yards and scoring allowed.

Broncos (8-8) at Raiders (7-9), 4:25 p.m. Fox: While 20 teams remain in contention for the postseason — tied for the most with one week remaining since there were 22 in 1982 — these are not two of them.

Eagles (11-5) at Giants (5-11), 4:25 p.m., CBS: Philadelphia has not won by more than one score since beating Miami the week before Halloween and has allowed an average of 31 points over the past five games (after allowing an average of 22.4 in the previous 11). On the other side of the ball, receiver A.J. Brown has had only one touchdown catch in the past seven games.

Rams (9-7) at 49ers (12-4), 4:25 p.m., Fox: The Rams appeared to be headed nowhere when they were 3-6 at midseason. Since then, they’ve lost only in an overtime shootout with the Ravens. Two of Sean McVay’s most important players on offense have been running back Kyren Williams (the 164th pick in the 2022 draft) and wide receiver Puka Nacua (the 177th pick in the 2023 draft).

Cowboys (11-5) at Commanders (4-12), 4:25 p.m., Fox: Dak Prescott and CeeDee Lamb saved the offense, which couldn’t muster much yardage with running plays, against Detroit. Tony Pollard had only 49 yards (with the longest run covering 18 yards) on 18 carries and was booed at times by the AT&T Stadium crowd.

Bills (10-6) at Dolphins (11-5), 4:25 p.m., NBC, Universo: The Dolphins’ pass rush has taken a hit with the loss of Jaelan Phillips and Bradley Chubb, and they’ve slipped from being 9-3 on Dec. 3 with a three-game lead over the Bills in the AFC East. But a victory would give Miami its first AFC East title since 2008 and a top two AFC seed for the first time since 1992 as well as its first 12-win season since 1990.
