The bout with Welsh boxer Howells was Cooney’s first defense of the Celtic super-featherweight title.

Cooney won the title with a win over Liam Gaynor in Dublin in November 2023, but spent a year out of the ring with a hand injury. He returned in October with a victory over Tampela Maharusi.

“He was just a lovely kid,” former boxing world champion Barry McGuigan told BBC Radio 5 Live. “It’s shocking and sad and heartbreaking.”
