I heard the ko occurred when he heard there was a special burger deal at McDonald's and he ran into the door trying to get in.
according to all the anonymous rumors AJ and Ruiz have both been KTFO with their headgear on while sparring with Dustin Nichols!! Maybe they barred him from the free Lamb Chops and Camel Milk Buffets!?
Nichols challenged Ruiz to a Pie Eating Contest and Ruiz Won!!! but needed a nap to process the millions of calories he consumed!
