KANSAS CITY, Mo. (AP) – Patrick Mahomes threw four touchdown passes to Travis Kelce, the Chiefs overcame an early 17-point deficit along with a dubious roughing-the-passer penalty, and Kansas City extended its mastery of the Las Vegas Raiders, holding on for a 30-29 victory. The Raiders had a chance to march for the winning field goal, but a pass to Davante Adams that was ruled a catch was overturned by replay, which showed him stepping out of bounds. That brought up fourth down in the closing seconds, and Derek Carr’s final pass fell incomplete to allow Kansas City to hold on.
