Lucas Browne is eager to reclaim his old WBA "regular" heavyweight title.

Earlier this month, the 43-year-old Browne pulled off a big upset when knocked out the heavily favored Junior Fa in one round. Fa was dropped twice before the contest was waved off.

The bout received a lot of attention, as it was part of the George Kambosos vs. Devin Haney undercard at Marvel Stadium in Melbourne.

Coming off the big win, Browne is hoping for one final run at a world title.

He admits that his pre-fight preparations have been tough, but he was actively working on the right hand that took down Fa.

"Because I'm in Perth, the caliber and quality of sparring partners isn't the highest. I can get numbers, but I have to get three or four and they all do a round at once, or something like that. If I go east, over to Sydney, Queensland, there's better quality sparring but all that costs money and time etc," Browne told The Sun.

"So when I do throw my right hand - if I do in sparring - it's more like a slap or a tap rather than an actual power punch. I think because I did that for some many years, I sort of brought that into my fights almost. I still jab nice and hard and stiff but when I throw my right I'm either not in the right position or I'm just not ready as I don't throw it enough.

"But I went into the Fa fight thinking, 'I'm just gonna throw it'. And now I'm going to throw it like that in sparring to make sure I'm ready."

Also this month, 24-year-old Daniel Dubois traveled to Florida to capture the WBA "regular" title with a knockout of unbeaten Trevor Bryan in four rounds.

Browne, who is well known by UK fight fans, is hoping to get the opportunity to face Dubois in the near future.

"My manager is onto it at the moment. Going into the Fa fight, I was top 15 in the WBA. Now defending that title I'm assuming I might bump up one or two places there. I am eligible and I would love to fight for my old title and actually give it a good go," Browne said.

"Dubois is very good, don't get me wrong, but I'm not afraid of the man, I'd defiantly come to bang, come to win. I want to win my old title back. It is something I am chasing."
