Australian superstar Tim Tszyu is preparing for a very action-packed battle with top junior middleweight contender Brian Mendoza.

Their fight was officially announced to take place in Australia on Sunday, October 15. Tszyu's last few fights have been carried on Showtime. Due to the time difference, the upcoming contest would happen on October 14 in the United States.

Tszyu will make the first defense of the WBO world title. The sanctioning body recently ruled that Tszyu would be elevated to full champion status - the moment current beltholder Jermell Charlo steps in the ring for his September 30th showdown with undisputed super middleweight champion Saul 'Canelo' Alvarez.

“We’re the two next pitbulls in the division... It’s a tremendous challenge and I look forward to taking it with both hands,” Tszyu said to Main Event.

“We’re the two top dogs in the super welterweight division because the other bloke did a runner. Number one versus number one."

Mendoza is 22-2 and highly regarded after several big wins in his current run - including a knockout of Sebastian Fundora.

Tszyu has no fear of Mendoza's punching power and plans to cap off another impressive performance.

“In all honesty, anyone that puts gloves on has some sort of power. Us boxers, we’re paid killers basically. It’s what we do. So I respect anyone who gets in the ring and I respect anyone that’s got power. His last performances, you’ve seen it, one-punch KOs and they’ve been against very, very top opposition. I’m not taking this lightly. But at the same time, people are dropping from me as well, their eyes are going googly as well," Tszyu said.

“In all honesty I couldn’t care less about what he’s done. I’m focusing on myself. I couldn’t care less about his knockouts and his ability."
