Boxer Curtis Harper has been criticised by his trainer for leaving the ring after the opening bell of a heavyweight bout in protest over pay
The 30-year-old American instantly walked out of the arena when the bell sounded for his bout against Efe Ajagba of Nigeria in Minneapolis.
Trainer Nate Campbell said he was "embarrassed" by his fighter's move.
"This man disrespected himself, his wife, the fans and me," Campbell posted on social media.
Journalist Jordan Hardy - who works for Premier Boxing Champions, which was broadcasting the fight - said Harper told her the walkout was because of money.
"He walked out of the ring because he's not getting paid enough to fight and that he wants respect," she wrote on social media.
'Why did he take the deal?'
Promoter Leon Margules told BBC Sport organisers had no idea of Harper's plan before the bout and confirmed the fighter received no payment as a result.
Harper now holds a record of six defeats and 13 wins, while Ajagba, 24, has six wins from six, including five knockouts.
