Sonny Bill Williams beat Francois Botha on points in Brisbane after the boxing bout was controversially reduced from 12 to 10 rounds during the fight.
The former All Blacks centre was hanging on by a thread in what turned out to be the last round and would almost certainly have lost if another two rounds had been allowed.
The judges awarded the fight to Williams 97-91, 98-94 and 97-91.
‘I love Sonny Bill, but this is bullshit,’ Botha said afterwards. ‘I beat him hands free!’
Earlier, Wallabies flyhalf Quade Cooper won his first professional fight in a first-round knockout of Australian Barry Dunnett.
There will be repeats of both fights on SuperSport at 3pm (SS5) and 7pm (SS1).
