Tim Tszyu has been mandated by the World Boxing Organisation (WBO) to fight for Brian Castaño’s super welterweight world title.
Tszyu’s manager Glen Jennings made the announcement on Facebook on Saturday.
“Some great news this morning,” Jennings wrote on Facebook.
“After weeks of hard work back and fourth with WBO, we received written confirmation that Tim is now mandated for a world title fight.”
Tszyu, 26, is unbeaten in 19 professional fights and is ranked as the number one contender by the WBO at super welterweight.
In the last 12 months, Tszyu has beaten former world champion Jeff Horn, plus Bowyn Morgan, Dennis Hogan and, most recently, Stevie Spark, all inside the distance.
Castaño fought a controversial draw in a unification fight with Jermell Charlo in July, which may yet be result in a rematch taking place.
The 31-year-old, with a professional record of 17 wins, 0 losses and two draws, was dismissive of Tszyu’s pedigree when asked whether a fight was in prospect earlier this month.
“Tim Tszyu is a good fighter, but I need a better fighter,” Castaño said in an interview with ESPN.
He was also dismissive of fighting in Australia, saying he preferred to work in the US.
Tszyu then accused Castaño of running from him in an interview with the Daily Telegraph, which Castaño described as “a joke”.
Charlo, who holds the other three major belts at super welterweight, the IBF, WBA and WBC titles, was also dismissive of Tszyu, saying on his YouTube channel that the Australian was not on a level to fight for a world title.
Tszyu was planing to fight again in November, which Jennings said was still the plan, with any world title fight would be most likely to take place in February next year.
“Firstly congrats to Tim, he has fought and beat all in front of him and thoroughly deserves this world title shot.
“I am a very proud Manager and mate, as we tick off yet another career milestone for Tim and our Team.
“It’s been an amazing effort from all involved … together we have achieved something special in a very short time.”
