Looking at the picture, the guy has rubber gloves on. So therefore he is probably the referee and he's somehow jumped in to stop a match and pulled the guy to guard would be my wild guess. I look forward to hearing the actual story of this.
Look at the picture for yourself... He doesn't have MMA gloves on (as the fighter does in his guard). He's got rubber gloves. Therefore he has to be either the ref or a doctor. Maybe he's doing a cursory cut inspection from guard? Maybe we'll start seeing guard as a standard position in all doctors offices around the world?
Peoples IS a ref. He started out reffing for Kickboxing. I believe he is now spending much of his time judging.
Elvis is correct. He has latex, medical gloves on. It looks like he stopped a fight "too soon" and the other fighter didn't like it so he went at Cecil and Cecil is just defending himself.
