Veteran Thiago Santos was looking to get his UFC record above .500 when he met former pro hockey player Steve Bosse on the main card of tonight’s (Sat., June 27, 2015) UFC Fight Night 70 from the Seminole Hard Rock Hotel and Casino in Hollywood, Florida.

He did just that in amazing fashion, flooring Bosse with an absolutely vicious first round head kick that stiffened the TriStar Gym fighter and required no follow-up shots. Watch the full fight video highlights of one the most devastating headkick knockouts in a long time above.
