Leave it to Nate Diaz to start some drama. Today at the UFC 141 pre-fight press conference, co-main event fighters Nate Diaz and Donald Cerrone weighed in and stared down. One thing or another (or maybe nothing at all) set Diaz off and he decided to knock down Cerrone’s famous cowboy hat. But of course it didn’t stop there, he then proceeded to shove Cerrone almost off the stage. Should be a good fight.
