David Tua's camp have challenged Sonny Bill Williams to a heavyweight title fight to "restore credibility" to the sport after the farcical finish to the Williams-Francois Botha bout in Brisbane on Friday night.
Promoter David Higgins, of Duco, said Botha was "robbed" in a points decision awarded over 10 rounds when everyone was expecting 12 rounds - and with Williams hanging on, desperately close to being knocked out at the end of the 10th.
"What I saw last night was an ageing warrior [Botha] who was robbed," said Higgins. "He is arguably of the same era as David Tua and I thought he was hard done by. There is overwhelming evidence that fight was supposed to go 12 rounds and for it to end like that certainly looked bad.
"It wasn't good for the sport, not good for the credibility of the sport. It's my understanding that all the marketing materials and communications and the programmes had it as 12 rounds. So we talked about it and thought we would give Sonny Bill the opportunity to go up against another warrior of the same kind of vintage.
"They always refer to Sonny Bill as the New Zealand heavyweight champion but that's a bit of a joke, too. I mean, how can you be the heavyweight champion and not rated in the top five? But Khoder Nasser [Williams' manager] has been using it as a marketing tool.
