Gavin Rees claims he will 'pour his heart and soul into his last pro bout' when he brings the curtain down on his career against Gary Buckland in Cardiff later this month.
The former WBA world light-welterweight champion bows out after 16 years in the paid ranks at the Motorpoint Arena on May 17, live on Sky Sports.
Rees, who also won British and European honours, takes on Buckland at the same venue which featured their 'Fight of the Year' contender in February which Buckland edged on a split decision.
"I will leave everything I have in the ring on May 17 and I am proud of everything I have achieved," said Rees. "Winning a world title was a dream come true and of course all British fighters want to win the British title and claiming that for the first time in 2010 was a huge honour.
"My trainer Gary Lockett has done a brilliant job getting me through training camps in the last few years but I can't keep doing it. I've had a fair few injuries and they are catching up with me.
"But I've still got a great fight left in me and I plan to empty everything left in me out in Cardiff and put on a real show for the fans who have been great to me.
"The first fight was a classic and you couldn't argue with the decision going either way. Of course I thought I did enough to get it but there were no complaints. Gary is a fantastic fighter and you know what you are going to get with us - all-action for 12 rounds.
"It'll be an emotional night for me knowing that it's the end of a brilliant road, so I want to bow out in style and say I ended my career with a great win in Cardiff."
Rees' last hurrah against Buckland is part of a great line-up in Wales as Lee Selby faces Romulu Koasicha in an official eliminator for the WBC featherweight title with the International belt on the line.
Nathan Cleverly makes his debut at cruiserweight against Guyana's Shaun Corbin with the WBA Inter-Continental title on the line while Liverpool's super- middleweight star Callum Smith defends his WBC International super- middleweight title against Swansea's Tobias Webb.
Dale Evans also takes on Mark Douglas and there's action for Chris Jenkins, Mitch Buckland, Robbie Turley and Alex Hughes.
