The Kansas City Chiefs had lost Patrick Mahomes to a concussion and were in danger of losing the game.

Then their defense and Chad Henne — their defense and Chad Henne? — along with a gutsy call by Andy Reid kept their hopes of a Super Bowl repeat alive, holding off the Cleveland Browns 22-17 on Sunday to advance to their third straight AFC championship game.

Harrison Butker added three field goals for the Chiefs, who nearly blew a 19-3 lead but survived to become the first AFC team to host three consecutive conference title games. They’ll face the Buffalo Bills next Sunday.

Baker Mayfield threw for 204 yards with a touchdown and a pick for the Browns (12-6), who were coming off their first playoff win since the 1994 season. But their inability to drive for the winning touchdown — they punted with 4:23 left in the game — and defensive letdown kept them from winning two playoff games in a season for the first time since 1950.

“It came down to us on defense and we let it slip,” Browns pass rusher Myles Garrett said. “We had two opportunities. We didn’t make it happen. It was right in front of us and we just — this time we didn’t get it done.”
