If Stephen A. Smith doesn’t have a voice on Monday’s episode of “First Take” on ESPN, here’s why.

The host took to social media on Sunday night to react to the wild Bills-Chiefs game at the end of regulation.

“I mean damn, I was ready to say ‘Josh Allen is the Tom Brady of the next generation’ because of what he pulled off, but then I saw Patrick Mahomes say, ‘Wait a damn minute, I ain’t done yet,”’ Smith yelled into the camera while watching the AFC showdown at home.

“I can’t believe what I am seeing,” he said as the game headed into overtime. “Lord have mercy — damn!”

The Chiefs overcame the Bills’ top-ranked defense in an unforgettable AFC thriller that ended in a 42-36 Kansas City victory.

Allen was brilliant throughout the divisional round matchup at Arrowhead Stadium in Kansas City — until Mahomes answered in overtime by forcing 75 yards in eight plays for a game-winning touchdown to Travis Kelce.

This is the second straight year the Bills season has come to an end at the hand of the Chiefs.

Smith promised to finish his rant Monday morning on ESPN’s “First Take.”
