KANSAS CITY, Mo. — After grinding along in a punt exchange — a combined eight before five minutes were gone in the second quarter — the Pittsburgh Steelers got the defensive break they hoped for in Sunday’s wild-card game against the Kansas City Chiefs.

On a first-and-10 from the Kansas City 31-yard line with 10 minutes, 41 second remaining in the second quarter, the Chiefs snapped the ball to wide receiver Mecole Hardman, who fumbled the hand-off to running back Darrel Williams.

Williams recovered the ball just before Steelers defensive tackle Cam Heyward knocked the ball free again. Steelers outside linebacker T.J. Watt scooped up the ball and ran 26 yards for the touchdown.

It gave the underdog Steelers an early 7-0 lead.

The Chiefs later responded when Patrick Mahomes flipped a pass to Jerick McKinnon, who scored from four yards out, and the game was tied 7-7. The Chiefs later took the lead when Mahomes found Byron Pringle for a 12-yard TD pass, and Kansas City led 14-7.
