Apparently, the rule "protect yourself at all times" applies to even the most timeless displays of sportsmanship.
Ibragim Khalilov disrespected an age-old gentleman's agreement at WBK 22 in China on Saturday, flatlining Bakhtiyar Barotov off a customary touching of gloves with a straight right hand to the button just three seconds into their fight.
The cheap shot earned Khalilov one of the quickest KOs in MMA history.
