Yordenis Ugas was taken to hospital following his fight with Errol Spence after the Cuban was left with one eye firmly closed.
Other than for brief moments in the first half of the fight, Ugas was dominated by his fellow welterweight world champion on Saturday night before the referee stopped the fight in the 10th round. The official had asked the ringside doctor to inspect Ugas' right eye for the second time - and on this occasion the bout was stopped.
Ugas was naturally taken to hospital to have his injury examined after insisting he wanted to hear the final bell. "I feel sad," he said. "I trained really hard for this fight. All my respect to Errol Spence, he’s a great champion. I’m just sad about what happened tonight. The referee stopped the fight, but I wanted to keep going to the end. I definitely had a chance to win the fight in the sixth round, but he recuperated well. Congratulations to him and his team."
