Mr. Valencia had no prior boxing experience and had never participated in a match before, his family’s lawyers, Nick Lasso and Ryan Zimmer, said in an interview on Monday.
In a statement on Friday, the president of the University of Nevada, Las Vegas, Keith E. Whitfield, said that the university was “committing all available resources to review the incident and determine how off-campus events like these can be as safe as possible.”
The university on Monday confirmed that Mr. Valencia had been a junior majoring in kinesiology, but declined to answer further questions.
The university’s website notes that over the last two years, the Kappa Sigma fraternity chapter had raised more than $45,000 through events like Fight Night.
Video footage of the evening match shows Mr. Valencia, clad in red boxing headgear, black boxing gloves and black shorts, darting around the ring and fielding blows to his chest and head. Less than five minutes after the match ended, Mr. Valencia collapsed, the family’s lawyers said, adding that emergency workers arrived more than 10 minutes later.
Mr. Valencia was pronounced brain dead before his death on Nov. 23, his family’s lawyers said.
In an interview with CNN on Monday, Cynthia Valencia, Mr. Valencia’s mother, questioned the training of the referee in the match in which her son had participated. She added that there were no paramedics on standby for the match.
Ms. Valencia said she had asked her son before the match why he was billed as the headliner, despite his lack of experience in the ring. He reassured her that all participants were amateur boxers, that he would be wearing headgear, and that he would be raising funds for charity, she said in the interview.
