HUNTINGTON, W.Va. - Brandon Doughty threw a Conference USA-record eight touchdown passes, the last in overtime to Jared Dangerfield followed by a 2-point conversion pass to Willie McNeal, that helped Western Kentucky slip past No. 19 Marshall 67-66 on Friday.
Marshall's Rakeem Cato had seven touchdown passes, but threw four interceptions.
Doughty broke the previous conference record of six touchdown passes set on eight occasions. He finished 34-of-50 for a total of 491 yards.
Doughty increased his FBS-leading TD pass total to 44.
Western Kentucky (7-5, 4-4) foiled Marshall's bid for the fourth perfect season in school history.
Marshall (11-1, 7-1) saw its 13-game home winning streak snapped and likely lost its chance to earn a place in the New Year's bowls. Marshall already has qualified for next week's conference championship, as the Thundering Herd will meet the winner of today's game between Rice and Louisiana Tech.
Cato finished 29-of-46 for 417 yards, helping him break Chad Pennington's school record for career passing yards.
