Ryan Burnett lost his World Boxing Super Series bantamweight quarter-final against Filipino-American Nonito Donaire after failing to come out of his corner for the fifth round.
The 26-year-old from Northern Ireland took a count of seven in the fourth round at the SSE Hydro, Glasgow after appearing to sustain a hip injury while in action against his 35-year-old opponent, a former world champion at four weights.
Burnett looked in distress as he returned to his corner at the end of the round and then retired for his first defeat in 20 bouts, leaving the talented veteran, who had shown his pedigree in the early stages, to be named WBA 'Unified' World Champion.
Donaire will take on WBO champion Zolani Tete in the semi-finals in early 2019.
