Matthew Macklin insists he's still capable of winning a world title despite suffering a crushing blow after he was knocked out in the 10th round of his WBC middleweight eliminator against Argentina's Jorge Sebastian Heiland at the 3Arena.
The tiring Macklin was 77-75 behind on all three judges' cards after the eighth round.
It was all over soon after that though as Heiland pinned Macklin in the corner and a left-right hook combination sent the Irishman sprawling and ended the contest.
"I'd been tiring for two or three rounds before that (knockout) really. Maybe I burnt up too much energy early on, maybe I'm getting old," smiled the 32-year-old Macklin, who started the fight as as odds-on favourite: . "I just faded a little bit.
"I thought I'd need to be beating him if I was as good as I was (previously). Taking nothing away from him, he fought a smart fight.
"He was the younger, fresher man. When he upped it, I wasn't able to. That was the difference.
"I'll have to analyse the performance and see where we go from here. I believe that at my best I'm world-class and capable of winning world titles."
Earlier on Saturday night's card, John Joe Nevin stopped Englishman Jack Heath in the first round to make it three wins from three in the professional ranks.
The Olympic silver medallist said: "It feels amazing. These are the fans who followed me out to London.
"I did okay for them there but some day I'd like to bring back a world title.
"I'd like to thank the high-performance unit - Billy Walsh, Gary Keegan and all the coaches for everything they've done for me. I wouldn't be here without them.
"I'm here to test myself. I've done everything I could as an amateur. Bring it on," added the Mullingar
Earlier again, Cork's Gary 'Spike' O'Sullivan floored Dublin's Anthony Fitzgerald (16-7) midway through the first round and the Dubliner was unable to beat the count.
