Pete Taylor was left disappointed over an "unnecessary stoppage" in his fighter's bout over the weekend.
Tyrone McKenna lost to Regis Prograis when the pair met in Dubai last Saturday night.
Despite being dropped in the second round McKenna battled on before a bad cut ended the fight in the sixth round.

Prograis had dominated the bout at the Dubai Tennis Centre but McKenna was starting to grow into the contest when it was halted.
McKenna told Eurosport: "He is world class. He is a heavy-handed man. Probably the hardest hitting man I have been in with. So it was tough every time you stepped in and got close to him.
"I thought I was getting into the fight as the rounds went on, but obviously I got the cut. I would love to have gone on with the cut.
"I have been cut in most fights but I wasn't able to carry on with this one which I am gutted about."
Taylor, the father of undisputed lightweight champion Katie, echoed the comments of McKenna.
The boxer's coach posted on Instagram: "A disappointing end to the week, with an unnecessary stoppage over a minor cut in the 6th round.
"Lion heart @tyrone_mc_kenna wasn’t given the opportunity to leave it all behind in the ring and go to war because of this premature stoppage. His time to shine will come again, fortune favours the brave."
Prograis - who is now mandatory challenger for the WBC world light-welterweight title - called out Jack Catterall who was sitting at ringside after the bout.
And he also had praise for the heart and resilience of McKenna.
"I knew he was tough," Prograis said.
"He's Irish and I knew he was a tough fighter. I dropped him but I knew he would get up, and when he got up I knew he wasn't hurt. I just had to keep doing my thing and keep boxing.
"I felt when I cut him, he kept pushing forward. Irish fighters keep pushing, so I had to change my game plan and get on the back foot and box some more."
Asked what fight he wants next, Prograis added: "I am just looking to improve and get better.
"I was world champion three years ago and I want to be world champion again. I have been at that level and I want to get back there again."
