Joseph Parker recently announced Tony Yoka as his sparring partner for a forthcoming unification with Anthony Joshua.
It what seems a smart move, the New Zealander drafted in the current and reigning Olympic gold medallist in his bid to defeat the 2012 champion.
The pair have eye-opening history too as Frenchman Yoka defeated Parker in the World Youth Tournament back in 2010 on his way to taking the crown.
Parker is hoping to knock Joshua off his perch as the top heavyweight in the world, whilst Yoka recently turned professional following his considerable amateur exploits.
Hayemaker-Ringstar signed Yoka, who defeated Parker as a 17 year-old, is 3-0 in the pro ranks on the back of making his debut in June of last year.
