FOXBOROUGH, Mass. — Stephen Gostkowski hit a 28-yard field goal as time expired, and the New England Patriots beat the Kansas City Chiefs 43-40 on Sunday night after blowing a big halftime lead.

Tom Brady passed for 340 yards and a touchdown and ran for another score in his 200th victory as a starting quarterback, tops all-time. Brady also passed former teammate Adam Vinatieri for most career wins in the regular season and playoffs combined with 227.

It was the first loss of the season for the Chiefs (5-1).

New England (4-2) led 24-9 at intermission, but Patrick Mahomes directed an impressive rally by Kansas City in the second half. He finished 23 of 36 for 352 yards in his first loss as a starting quarterback, with three of his four TD passes going to Tyreek Hill.
