nd horribly speaking, this is the photo of Russian fighter Maxim Dadashev who also died just a few days ago because of in-fight injuries. What a pair of tragedies! This is the photo of Santillan who was a former South American super-featherweight champion. Argentine boxer Hugo Santillan has died from injuries sustained during a title fight, just days after the death of Russian fighter Maxim Dadashev. The 23-year-old collapsed in the ring on Saturday shortly after his WBC Latino Silver lightweight bout with Eduardo Javier Abreu in Argentina ended in a draw. He was taken to hospital and underwent emergency surgery but died on Thursday. "Rest in Peace, Hugo Santillan," the World Boxing Council said in a tweet. Santillan is the second boxer to die from injuries sustained in the ring this week after Dadashev's death was confirmed on Tuesday. The 28-year-old had been hospitalised with bleeding on the brain after his IBF light-welterweight fight against Subriel Matias was stopped at the end of the 11th round last Friday. He underwent emergency surgery but failed to recover. Boxing promoter Kalle Sauerland tweeted on Thursday: "A sad, sad week for boxing."
