Joseph Parker has called on Sonny Bill Williams and Paul Gallen to settle their long-standing feud in the ring over three-minute rounds.

It came after Jai Opetaia last week called the former rugby league stars ‘soft’ for agreeing to clash over two-minute rounds.

Gallen and Williams have been tiptoeing around eachother for some time over a deal to square-off in the ring.

But last month, they finally put pen to paper on a contract that will see both former NRL players finally square off in the ring, with both set to bank $1million from the fight.

Despite excitement now beginning to build over the clash, Opetaia, the Ring and IBF Cruiserweight title holder, called on the pair to make a change to the fight’s scheduling.

‘It’s not an attack, I’m taking the piss – but two-minute rounds is soft, bro,’ Opetaia told News Corp.
