Rico Burton was fatally stabbed outside a bar in Altrincham, Greater Manchester in the early hours of August 21. Liam O’Prey, 21, has since been charged with her murder.
Tributes poured in for the 31-year-old, with boxer cousin Tyson Fury leading the way.
The two-time world heavyweight champion, from Wythenshawe, Manchester, has called for an end to knife crime in a post on his social media following the death of his cousin.
Today Mr Burton’s family and friends said an emotional goodbye to him, Manchester Evening News reports.
The service took place at St Michael’s Church in Urmston, Greater Manchester.
Mourners arrived for the service on carriages and trailers, one being pulled by a horse.
A trailer carrying a huge white flower arrangement for him was also spotted, while another carried flowers that spelled his name.
Dozens of people were expected to show up to pay their respects to Mr Burton at the service.
Shaun Egan, who previously trained Mr Burton alongside his brother Steve at Jimmy Egan’s Boxing Academy in Manchester, described him as “such a nice guy”.
“He was an absolute talent,” he said. “He was such a nice boy, he worked hard and had a great sense of humor.
“What happened is just awful. He was just a great guy. To hear he died like that is devastating.”
O’Prey appeared at Manchester Crown Court on August 26 charged with the murder of Mr Burton. He faces four counts related to the same incident.
Mr. O’Prey is charged with murder; unlawful injury with intent to cause grievous bodily harm; possession of a bladed item; namely a knife; and possession of cocaine.
He could be tried early next year. He was taken into custody.
A 17-year-old was also seriously injured in the incident and received “life-saving” treatment at the scene, police said.
