Heavyweight veteran Lucas Browne has promised to pull off a big win on June 5th, as part of the undercard to the lightweight unification between George Kambosos and Devon Haney at Marvel Stadium in Melbourne.

Browne (30-3, 26 KOs) will have a tough test ahead of him, as he will face tough New Zealand contender Junior Fa (19-1, 10 KOs).

Fa's only loss was a competitive decision to former WBO world champion Joseph Parker.

Last year, Browne suffered a knockout loss at the hands of Paul Gallen - but then bounced back with a knockout win in December.

At 43-years-old, Browne can't afford another defeat.

“I would love nothing more than to fight for another world title and Junior Fa is standing in my way. If I can put him away early, that will send a message to the boxing world that I am far from finished. He has only lost once in his career, to Joseph Parker. I plan to hand him his second defeat,” Browne said to Fox Sports.

Although he's a solid favorite to win, Fa is not overlooking the task ahead with Browne.

“I 100 percent back myself, but I’m not taking Lucas lightly as he is a former world champ and was stopped by (Paul) Gallen with some illegal blows, so I don’t count that as a loss for him," Fa said.

“He has his power and we saw him use it to KO his last opponent. I’ll be getting the best Lucas Browne for this fight as I’m in the way of him being a contender again. It’s a huge opportunity for him and it’s going to be a tough fight.”
