Reid told Mahomes to 'be the Grim Reaper' with 13 seconds left

Kansas City Chiefs head coach Andy Reid had advice ready for Patrick Mahomes when the Buffalo Bills scored a go-ahead touchdown with 13 seconds left in regulation of the AFC divisional round.

"When it's grim, be the Grim Reaper and go get it," Reid said postgame, per CBS Sports. "He did that. He made everybody around him better, which he is great at. He just does it effortlessly. When it gets tough, he's gonna be there battling and the players appreciate that."

The Chiefs looked all but dead after Josh Allen threw his fourth touchdown to Gabriel Davis in the dying seconds of the fourth quarter to put the Bills ahead 36-33.

Mahomes responded with a quick pass to Tyreek Hill that went for 19 yards before calling the Chiefs' first timeout with eight seconds left. He found Travis Kelce for 25 yards on another short pass before taking their second timeout with three seconds on the clock. The chunk gains set up Harrison Butker for a 49-yard field goal attempt, which he nailed to force overtime.

The Chiefs got the first possession of the extra session after winning the coin toss, and Mahomes threw a game-ending touchdown before the Bills could get their hands on the ball.

"The one thing that I love about this team is they didn't flinch," Reid said, according to the Washington Post's Nicki Jhabvala. "They kept focus, nobody threw in the hat and quit. They just kept battling."

Kansas City won 42-36 and will host the Cincinnati Bengals in the AFC Championship Game.
