Lyoto Machida and Yoel Romero may have headlined UFC Fight Night 70 on Saturday night, but the card's most impressive moment came much earlier, as Thiago Santos viciously knocked out Steve Bosse with a picture-perfect headkick. You can check out the cringe-worthy video above, courtesy of UFC on Fox Sports.
For years, Bosse was a highly regarded light heavyweight prospect, but a lack of commitment to the sport saw him fight just once since 2011. Visibly rusty, the former semi-pro hockey enforcer carried his hands low and held his chin high. Santos, an opportunistic finisher, identified the opening and cracked him with a brutal kick that landed shin-to-temple.
