Shannon Briggs has made a return to sparring ahead of a potential comeback fight against Quinton 'Rampage' Jackson later this year.
The former heavyweight star has been locked in talks to face former MMA star Jackson after the pair clashed during a weigh-in for the Triad Combat event last year.
He is looking to organise an exhibition in a similar way to the mega-money clash between Mike Tyson and Roy Jones Jr which was staged by Triller.
