Apparently Dana White didn't scold Conor McGregor during the UFC press conference, he just told him his zipper was down.
During the UFC's "Go Big" press-conference that featured the promotion's biggest stars, Conor McGregor took the mic and started talking smack about several stars and champions from different divisions. He went off on Donald Cerrone, Rafael Dos Anjos and Jose Aldo among others, but then Dana White came over and whispered something to McGregor.
While many assumed it was the UFC president scolding McGregor about something he said during the lengthy rant, it was apparently far from it.
