Former UFC fighter and "The Ultimate Fighter 2" cast member Mike Whitehead (23-6) rebounded from a July loss to Renato "Babalu" Sobral and picked up his 14th victory in his past 15 fights with a first-round submission victory over Leo Pla (4-2) on Wednesday.
The fight capped off the M-1 Challenge 8th Edition, which took place in conjunction with the Affliction Entertainment at Harrah's North Kansas City Casino.
The M-1 Challenge, which recently partnered with Affliction, is a team-based international competition designed for young fighters who want fight experience. The top fighters can win spots on major M-1 fight cards.
Whitehead, a three-time All-American wrestler at the University of Missouri, competed in one of the night's two superfights, which showcase established stars. He submitted Pla with a guillotine choke just 80 seconds into the fight. It was his 12th submission victory in 23 pro wins.
