Five days after fighting for his life while in a comatose state, Filipino boxer Karlo Maquinto passed away Friday morning at approximately 10:15am Philippines time, according to reports from GMA News.

Maquinto was 21 years old.

The tragic news comes less than a week after the Filipino flyweight collapsed in the ring moments after the conclusion of a four-round bout with Mark Joseph Costa in Caloocan City, Philippines on January 28. Maquinto suffered two knockdowns in the opening round before bravely battling back to pull even on two scorecards.

The bout resulted in a majority draw, the lone blemish on his ring record (6-0-1, 4KO) in a career that began less than a year ago.

Upon collapsing and losing consciousness, Maquinto was immediately rushed to FEU Hospital in Quezon City, according to an after-the-fact report from Boxingscene.com reporter Ronnie Nathanielz. A blood clot on his brain was the cause of his slipping into a coma, but that he was medically declared to be too weak to survive an operation.
