A fight between TUF Brazil 3 coaches Chael Sonnen and Wanderlei Silva has finally been made official for what’s expected to be a ‘Fight Night’ event in Brazil on May 31st.

The bout has been anticipated for some time, but for reasons that haven’t been disclosed, up until last night the promotion hadn’t been able to confirm whether the fight was going ahead or not.

That had prompted Sonnen to claim that Silva was trying to get out of having to fight him, but it appears that was not the case and they will now be able to settle their differences once and for all.

Meanwhile, a new sneak-preview of the upcoming TUF Brazil 3 episode on the UFC’s ‘Fight Pass’ service shows another physical confrontation between the two rivals as Sonnen calls Silva “stupid” during a heated argument and gets shoved in return.

Check out the new footage below.
