A proposed boxing match between former world title challenger Frans Botha and rugby star Sonny Bill Williams could be in jeopardy. Botha and Williams are slated to meet in Brisbane, Australia on November 24, but Williams has sustained an injury last weekend that could torpedo the match. As a boxer the 27-year-old Williams, has compiled a 5-0, 3 KOs record since making his pro debut in 2009, while continuing his rugby career. He won the New Zealand heavyweight title in his last fight. The 44-year-old Botha is 48-8-3 with 29 KOs.
