KANSAS CITY, Mo. — Courtland Sutton and the Broncos were still celebrating his 32-yard touchdown catch in the second quarter Sunday when the tremor preceding the earthquake rippled. It barely registered, but maybe it had been building for some time. Weeks, even. On Wil Lutz’s extra point, Chiefs linebacker Leo Chenal bull-rushed off the left side of the Broncos’ protection and knocked Alex Forsyth down to his back. No problem, though.
