Tim Tszyu will headline the first US pay-per-view of his career when he takes on Sebastian Fundora in Las Vegas on Saturday, March 30 (Mar. 31 in Australia).
With the WBO and WBC belts on the line, the Australian is aiming to unify a division like his father – Hall of Fame boxer Kostya Tszyu – did.
Kostya hasn't seen his son fight in person since 2016 but mixed reports have swirled about his possible attendance at the upcoming bout.

Will Kostya Tszyu be at Tim Tszyu’s next fight?
According to Fox Sports Australia, Kostya was set to attend his son's fight at T-Mobile Arena in Las Vegas.
However, just one day after the initial reports, Tim himself poured cold water on the possibility, declaring his father was "not coming."
Had Kostya attended, it would have marked just the second time the 54-year-old has watched Tim fight professionally live.
In 2016, Kostya surprised his son one day before his pro debut against Zorran Cassady.
The pair had not seen each other for four years.

While Tszyu won the fight, he decided to ban his father from attending any future fights.
"He was a nightmare – a pain in the ass!" Tszyu told Sporting News in 2021 about Kostya’s ringside presence.
Tim said he struggled with Kostya's persistent yelling during the fight.
"That was the last time. I love my Dad’s support and I respect him, but it was a bit difficult," he added.
"Maybe next time I’ll give him one of those suites far away and he can watch with binoculars."
