If it is a punch thrown after the fighter had been downed for any length of time it calls for auto DQ....EG a fighter hits the canvas even by 1 knee the opp stops in front pauses then throws the shot...

In thought the fighter throwing the shot paused because they realize they had a downed opp then decided to throw anyway....

If an opp falls in the middle of a combo and gets a shot it is usually ruled accidental and something that happened in the momentum of a flurry.....

Anyone remember Jones DQ against Griffin?

Most of the time though a DQ will only be called if the fighter has been dirty all night, or inflicted damage to the opp to where they can not continue like Dirrell claimed...

Though in the end it is the refs call and Saturday it was a bad bad ref....
