Fox News reports that a 43-year-old tennis player died on Sunday after collapsing during a match. 

The individual is Ryan Vannah, a lifelong tennis player from Las Vegas Nevada.

What happened?

Details about the incident have been reported by the Las Vegas Review-Journal.

According to the Journal, the incident took place on Sunday afternoon at the Red Rock Country Club, where Vannah’s teams had recently won a couple of national championships. There, Vannah was part of a mixed doubles tennis match.

During the tiebreaker of the contest, Vannah, according to the Journal, suddenly dropped down to a knee. Vannah then placed his hands on the court before laying down.

There were doctors at the event, and, recognizing what was happening, they rushed to Vannah and began to perform CPR on him. They continued to give him medical attention for the next 55 minutes.

It turns out, however, that Vannah’s heart had stopped, and, despite the doctor’s efforts, they were unable to start it back up again. Vannah was taken to the Summerlin Hospital and Medical Center, and, there, he was pronounced dead at 5:10 p.m.

The cause of death has yet to be confirmed

At the time of this writing, Vannah’s cause and manner of death have yet to be confirmed by the coroner.

It has been revealed that Vannah’s family had a history of high blood pressure. Vannah, in fact, was on medication for it. But, according to his family, as far as they could tell, Vannah had the condition under control.

Vannah’s sister, Tami Vannah Kang, is quoted as saying, “He took impeccable care of his health. He was so fit. He lifted weights. He looked like a bodybuilder to me. He was huge. We did not see this coming.”

Personnel at the Summerlin Hospital, however, have expressed their opinion that Vannah was actually on the wrong blood pressure medication.

But again, the coroner has not released his report. And so, what led to Vannah’s death remains unknown.

Who was Vannah?

A native of Las Vegas, Nevada, Vannah was part of a family of lawyers and doctors. He, himself, however, took a different path, working in security and as an athletic trainer before deciding to pursue tennis full-time.

Vannah had a passion for the sport, and he was highly regarded within the local tennis community. He is reported to have shared his passion for tennis with others, including children at local elementary schools, whom he taught to play the game.
