A similar thing happened during a heavyweight encounter between Chris Barnett and Martin Buday.
Aljamain Sterling, the first man in UFC history to become champion via DQ due to an illegal strike, has criticized the current rules allowing the referee to adjudge whether an illegal strike is intentional or otherwise.
In his first fight with Petr Yan last year, ‘No Mercy’ hit Sterling with an illegal knee to the head, rendering him unfit to continue.
