The Chiefs had won five straight against the Texans, including a divisional playoff matchup last January on their way to another Super Bowl appearance. But they were two different teams entirely when they returned for the rematch on Sunday night.

The streaking Texans were trying to keep their momentum going, and perhaps join a rare club of teams that includes Houston’s 2018 version that started 0-3 and made the playoffs. And the once-dominant Chiefs were simply trying to stay in the postseason fight amid a dismal season marked by injuries, underwhelming performances and too many mistakes across the board.

The first half turned into a microcosm of all of it.

Stroud, who played so well against Indianapolis last week in his return from a concussion, connected with Collins for a 46-yard gain that set up Ka’imi Fairbairn’s field goal, and a 53-yard catch that led to a short touchdown toss to Woody Marks.

Meanwhile, the Chiefs sustained two more significant injuries, this time to left tackle Wanya Morris and cornerback Trent McDuffie, leaving them without their best defensive back and Mahomes working with an offensive line consisting of three backups.

Kansas City wound up with 98 first-half yards and trailed 10-0 at the break, only the fourth time with Mahomes at quarterback and the second time in the regular season that the Chiefs had been shut out in the first half.

The Chiefs’ defense held its own, though, forcing Stroud into eight consecutive incompletions to start the second half. That allowed Mahomes and the offense to pick away at the deficit, first on Kareem Hunt’s TD run and then on Harrison Butker’s tying field goal.

Ultimately, the game hinged on two fourth-down decisions in the first quarter.

With the score still 10-10, the Texans had fourth-and-1 at their own 35 and punted. The Chiefs were then held to fourth-and-1 at their own 31, chose to go for it, and watched Mahomes throw incomplete with just over 10 minutes remaining.

Six plays later, Ogunbowale plowed into the end zone from 5 yards out to give Houston the lead again.

The Chiefs failed on fourth down again moments later, when Rashee Rice dropped a wide-open pass that would have produced a first down. And after Kansas City got the ball back one last time, Mahomes was picked off to end any hope of a comeback.
