This may have already been discussed but I just now watched the fights.
Did Barao somehow get a sponsorship exemption from the UFC to have a TNT Energy Drink sponsorship on his fight shorts? Or did he just do it without their approval? 
TNT sponsored the UFC in Brazil. The UFC probably has them on an official sponsor list the same they have Budweiser and Harley Davidson. This is just my guess 
I was wondering the same thing.
Yeah I remember something about fighters who are sponsored by official UFC sponsors getta secondary sponsor patch on there shorts, Conor had a Monster patch on his shorts UFC 189. Im pretty sure Cerrone will have a Budweiser and Hendricks a Fram patch on there shorts
If Barao went renegade, they will make an example out of him.
