Sonny Bill Williams has revealed that he will quit boxing if he gets knocked out by Francois Botha.
After just five professional fights, Williams' quest for boxing credibility reaches a crossroads when he takes on the South African in Brisbane on February 8.
A veteran of 60 pro fights and having been in the ring with Mike Tyson, Lennox Lewis and Evander Holyfield, Botha is a risky opponent for Williams at this stage of his fledgling career.
Victory against Botha would boost his boxing profile internationally but the dual-code superstar revealed that defeat will see him throw in the towel and concentrate on his return to the NRL with the Sydney Roosters next month and his long-term footballing career.
"If I get knocked out then that will probably be the end," Williams said yesterday.
"Right now I can see myself doing boxing fulltime in the future, but for that to come to fruition I need to fight guys like this and beat them, otherwise it's a waste of time.
"If this doesn't go too well I could just stay in one sport.
"If I lose this fight I will definitely be upset because I know it will probably be the end of it.
"And if I win, then it opens doors."
