Argentine boxer Hugo Santillan has died after a brain injury suffered during his fight on Saturday — just days after the death of Russian fighter Maxim Dadashev.

The South Amarican super-lightweight slugged out a draw with Eduardo Javier Abreu and died after a brief coma. After the bout, Santillan passed out in the ring while awaiting the judges’ verdict.

Doctors rushed to his aid as they fitted him with an oxygen mask and rush him to hospital. Santillan underwent brain surgery for a clot, but he suffered two cardiac arrests fighting for his life.

Santillan’s passing was confirmed by the WBC.

“RIP Hugo Santillan,” the boxing organization said in a statement. “He passed away from injuries suffered during Saturday’s fight which ended in a draw. We join Hugo’s family and friends in grief, support and wish prompt resignation.”

Santillan died with a 19-6-2 record, with his fatal draw coming in a fight for the WBC Latino Silver lightweight title.

The 10-round fight took place at the Club Atletico San Nicolas in Buenos Aires. The shock news comes as the boxing world was still reeling from the loss of Dadashev.

The late Russian, 28, underwent a serious brain surgery following the 11th-round defeat in an IBF light-welterweight title eliminator in Maryland. Dadashev had the right side of his skull removed to ease brain swelling after suffering a subdural haematoma in Friday’s brutal clash.
