Russian boxer Maxim Dadashev died Tuesday after suffering a similar brain injury during Friday's fight in Maryland against Subriel Matias of Puerto Rico. He was 28.
Santillan (19-6-2), a super lightweight, made his pro debut in 2015. Eight of his 19 victories came by knockout. He was the son of fighter Hugo Alfredo Santillan and was from the same region, Santa Fe, as Marcos Rene "Chino" Maidana.
According to ringside reports, Santillan's nose began to bleed in the fourth round and, though he raised his arm in victory after the fight, he passed out as the judges were announcing the draw -- scored 95-95, 93-97 and 96-94 -- against Abreu (10-1-1).
"Upon admission to the hospital, he had successive kidney failure and he did not come out of his coma," Olocco said. "He had swelling of his brain and he never recovered consciousness. The swelling continued to worsen, and it affected the functioning of the rest of his organs."
