Australian boxing champion Skye Nicolson scored a huge victory over Sabrina Perez on Saturday night, but it was overshadowed by the shocking death of her opponent’s trainer and husband, Diego Arrua.

Arrua was ringside for his partner’s interim WBC featherweight title fight before suffering a fatal heart attack in Perez’s corner.

His collapse occurred between the ninth and tenth rounds of the fight, and he was unfortunately unable to recover.

The tragic news was confirmed by WBC President Mauricio Sulaiman on social media, announcing that Arrua had passed away in Tijuana.

“It is with great sadness that we have been informed of the sudden death of Argentine coach Diego Arua, who suffered a devastating heart attack during Sabrina Pérez’s fight in Tijuana,” Sulaiman wrote.

The 58-year-old collapsed during the ninth and 10th rounds of Perez’s defeat on Friday
