KANSAS CITY, Mo. (AP) — The Texans and Chiefs set a postseason record for combined points in the first half on Sunday when the Chiefs rallied from a 24-0 first-quarter deficit to take a 28-24 lead into the locker room.

The 52 points eclipsed the 49 set by the New Orleans Saints and Arizona Cardinals in the divisional round on Jan. 16, 2010. It fell just short of 56 points for any half, set by the Cardinals and Green Bay Packers in the wild-card round a week earlier.

The Texans missed a chance to make it 28-27 when Ka’imi Fairbairn missed a 51-yard field-goal attempt on the final play of the half.

The Chiefs fumbled a punt return, had their own punt blocked for a score and committed plenty more mistakes in becoming just the fourth home team in NFL history to trail 21-0 after the first quarter. But the Texans called a fake punt in the second quarter and were just as sloppy in allowing Kansas City to mount the biggest comeback in team history.

Chiefs quarterback Patrick Mahomes threw three touchdown passes to Travis Kelce in the second quarter, and his four total TD throws matched the playoff record set by the Redskins’ Doug Williams in the Super Bowl in January 1988.

Kelce became the first pass-catcher with three touchdowns receiving in a single quarter in postseason history, while the tight end became one of 16 players with three TDs total. Nobody has had four TD catches in a playoff game.

The Chiefs had the ball a mere 4 minutes, 50 seconds in the second quarter. They needed just 16 plays to score four TDs.
