The boxing world is dealing with its second tragedy in one week -- 23-year-old Argentinian fighter Hugo Santillan died on Thursday after suffering injuries during his fight over the weekend.
Santillan fought Eduardo Javier Abreu for the WBC Latino Silver lightweight title in Buenos Aires on Saturday. The bout ended in a draw after 10 violent rounds -- but it was clear something was wrong.
Santillan collapsed in the ring as the announcer presented the results of the fight ... and doctors rushed to give him oxygen. He was stretchered out of the venue and taken to a nearby hospital.
