(AP) — Patrick Mahomes ran for the tying touchdown and 2-point conversion late in the fourth quarter, Harrison Butker atoned for two earlier misses by kicking the go-ahead field goal in overtime, and the Kansas City Chiefs beat the Tennessee Titans 20-17 on Sunday night. Mahomes was 43 of 68 for 446 yards with a touchdown and an interception, and Mecole Hardman also had a TD run, as the Chiefs (6-2) rallied from a 17-9 deficit to beat the Titans for only the second time in the last seven meetings. Chiefs coach Andy Reid improved to 21-3 coming off a bye by beating a franchise that has long been his nemesis. He was just 2-9 against the Titans — heck, Reid has three wins against the Chiefs — including a 27-3 loss in Nashville last year.
