Light flyweight Luis Yanez will fight his removal from the U.S. Olympic team after requesting a hearing next week to appeal USA Boxing’s decision.

Yanez, a 106-pound fighter from the Dallas area, was kicked off the team Monday after he skipped three weeks of workouts in Colorado Springs during June without telling the coaching staff where he was, coach Dan Campbell said.

Yanez, who also missed a training trip to Argentina during his absence, later said he was in Texas to support his sister while she underwent medical treatment. Campbell said the U.S. coaching staff couldn’t reach Yanez despite repeatedly demanding his return to training camp.

In an interview with The Associated Press, Campbell accused Yanez of misleading the U.S. coaches during his absence, calling Yanez “one of the biggest liars I’ve ever met.”

“I’m very disappointed that someone at that level will come out and say something like that, whether it’s true or not,” Michael Montoya, a Yanez family spokesperson, told the AP on Wednesday. “For him to come out and start name-calling and start calling the captain of the U.S. boxing team a liar, that’s disturbing and disappointing.”

Campbell also said Yanez was lying about being a team captain. His rotating captaincy of the team ended in February.

Montoya said Yanez is training in the Dallas area in hopes of rejoining the team. He is entitled to an appeal hearing in front of USA Boxing’s disciplinary committee, and Yanez has retained lawyer Domingo Garcia to represent him.

If that hearing fails, Montoya said Yanez will request an outside arbitration hearing, which is his right under USOC policy.

“Although this is a negative, he’s trying to stay positive,” Montoya said. “He’s still working out and getting ready.”

Without Yanez, the U.S. would send just eight boxers to the Olympics _ the smallest team since the 1948 London Games. Americans have won 111 medals in Olympic competition, more than twice as many as second-place Cuba, but the U.S. has just one gold medal in the last two Olympics.
