UFC heavyweight Walt Harris has been disqualified during the UFC 217 prelims, after a sickening late head kick on rival Mark Godbeer.
Godbeer was reeling from a low blow from his opponent, before the referee called time on the fight.
However despite the referees loud calls of "time, time, time", Harris didn't take a backwards step, moving towards a defenceless Godbeer before unleashing a disgusting late kick.
"I called time!" the referee yelled at Harris as he sent him back to his corner, before checking on the welfare of Godbeer.
Commentator Joe Rogan described the late hit as a "blatant cheap shot".
Doctors then pronounced Godbeer unfit to continue, leaving the referee with no choice but to DQ Harris, who was clearly disappointed with the decision.

After the fight, Harris said his opponent was looking for a way out.
The incident was eerily similar to one seen earlier this year, as Germaine de Randamie benefited off two ugly late punches to defeat Holly Holm in the inaugural women's featherweight championship at UFC 208.
Watch that incident in the video below.
The heavyweight bout was on the preliminary card ahead of the highly anticipated middleweight championship fight between champion Michael Bisping and the returning Georges St-Pierre.
The Canadian marked his comeback with an incredible choke submission in the third round of the bout against the Briton.
The men's bantamweight title bout threw up another instant classic as TJ Dillashaw floored Cody Garbrandt halfway through the second to win by knockout and reclaim the belt he lost to Dominick Cruz in January 2016.
Earlier in the evening, challenger Rose Namajunas pulled off a stunning victory to wrest the women's strawweight crown from Joanna Jedrzejczyk, felling the Pole with a thundering left hand to finish the fight by knockout 3:03 into the first round.
