Junior Dos Santos has uttered the words that Dana White will love to hear, revealing he will fight Jon Jones if the situation arises.

Dos Santos is currently the King of the UFC heavyweight division, having made a first successful defence of his belt against Frank Mir. He is expected to rematch Cain Velasquez next, after which there are few obvious challengers.

The clamour is growing for Jones, the light-heavyweight champion, to step up in weight to fight the Brazilian as he too finds himself running out of title contenders. Jones fights Dan Henderson at UFC 151, and he has confessed a desire to switch weights in 2013.

The major stumbling block appeared to the identity of the heavyweight champion, namely Dos Santos, who Jones likens to a brother. However, Dos Santos admits he would fight Jones if called upon to do so.

"Jon Jones is really good. He's really good. It's different, for sure. If he comes up to the heavyweight division, it's gonna be tough for us, for sure," the Brazilian told MMA Uncensored Live.

"I really like him, but if he comes up to the heavyweight division, and he gets the chance to fight for the title, we're gonna fight. I will give my best to beat him.

"It doesn't matter who my opponent is. If it's gonna be him, I don't care."
