Sevilla defender Antonio Puerta died Tuesday, three days after collapsing on the field during his team's Spanish league match against Getafe, Spanish news reports said.
A statement by his managers was expected to be released shortly.
Puerta lost consciousness and fell near his own goal Saturday in the 31st minute, but was able to walk off minutes later after being treated by team doctors.
He collapsed again in the locker room before being taken to the hospital, where he has been since.
