There seems to be some lasting hostility between UFC lightweight champion Rafael dos Anjos and former champ Anthony Pettis.
In March at UFC 185, Dos Anjos battered Pettis over five rounds to take the crown. According to No. 1 lightweight contender Donald Cerrone, Pettis even offered to help him prepare for his upcoming title challenge against Dos Anjos at UFC on Fox 17 in December.
"Anthony told me, he said, 'Hey Cowyboy, you need me to come down and train you for Dos Anjos," Cerrone told UFC commentator Joe Rogan.
