Benitez was 27.
The death was a shock to his family and team, and came after complications related to appendicitis. He had been rushed to the hospital with severe stomach pain.
Doctors discovered his appendicitis had become peritonitis, which led to the respiratory arrest that ended his life, his father-in-law said.
Benitez played for El Nacional in Ecuador and Santos Laguna in Mexico before a season at Birmingham City in the Premier League. He later returned to Mexico with Club America. He also played at the 2006 World Cup for his home Ecuador.
At the time of his death, he was playing in the Qatari league with Eljaish. He had played his first game with the club the day before he died. No information has been released to determine whether conditions in Qatar were a factor in his death. Benitez had not previously complained about health problems.
