Patrick Mahomes has allayed concerns about his ailing ankle as the Kansas City Chiefs took a big step toward securing the No.1 seed in the AFC playoffs with a 27-19 victory over the Houston Texans.

Chiefs quarterback Mahomes threw for 260 yards and a touchdown while also running for a touchdown of his own in Saturday's home game.

The AFC West champion Chiefs (14-1), who have won four straight against the AFC South champion Texans (9-6), can clinch the postseason bye if Buffalo lose to or tie New England on Sunday. If the Bills win, Kansas City can wrap it up by beating Pittsburgh on Christmas Day.

There were questions early in the week about whether three-time Super Bowl winner Mahomes would play after sustaining a high ankle sprain late in last week's win over Cleveland.

But the two-time MVP was off the injury report by Friday, and Mahomes showed no problems on the Chiefs' opening drive Saturday, finishing it off with a 15-yard scramble to the end zone.

"I ask a lot from the guys around me. I feel like if I'm going to ask them to play through pain and nicks and bruises, I've got to do it as well," Mahomes said. "That's something that I pride myself on is being out there with my guys."

Xavier Worthy had seven catches for 65 yards and a touchdown, Kareem Hunt ran for 55 yards and another score, and Marquise Brown had five catches for 45 yards for Kansas City in his first game this season after recovering from a shoulder injury.

C.J. Stroud had 244 yards and two touchdown passes with two interceptions for Houston, though one of those TD throws came at great expense. Tank Dell, who had six catches for 98 yards, hurt his left knee on the play and was carted from the field.

Dalton Schultz also had a TD reception for the Texans. Joe Mixon was held to 57 yards rushing.

Pop star Taylor Swift was on hand for the Chiefs' regular-season finale. She has been spending more time with her boyfriend, Chiefs tight end Travis Kelce, in Kansas City since she wrapped up her Eras Tour on December 8.

In Saturday's other match, Lamar Jackson passed for three touchdowns and Derrick Henry rushed for 162 yards on 24 carries as the Baltimore Ravens clinched an AFC playoff spot with a 34-17 victory over the visiting Pittsburgh Steelers.

Marlon Humphrey returned an interception for a touchdown as Baltimore (10-5) defeated Pittsburgh for just the second time in the past 10 meetings. Isaiah Likely, Rashod Bateman and Mark Andrews caught scoring passes and Zay Flowers had five receptions for 100 yards.

Jackson completed 15 of 23 passes for 207 yards and was intercepted once while improving to 2-4 as a starter against the Steelers.

Russell Wilson was 22-of-33 passing for 217 yards, two touchdowns and one interception as Pittsburgh (10-5) missed a chance to clinch the AFC North.
