French Tennis Player Mathieu Montcourt Dead At 24

French tennis player Mathieu Montcourt, who was recently banned for betting on matches, has died. He was 24. The French tennis federation said Tuesday that Montcourt died overnight but the cause of death is not yet known, and an autopsy will be conducted.

French media reported the 119th-ranked Montcourt was found dead by his girlfriend in the stairwell of his Paris apartment. In May, Montcourt was handed a five-week ban and fined $12,000 for betting on other matches.

“It is with great sadness that the French tennis federation has learned of the sudden death of Mathieu Montcourt,” the French tennis federation said. “Mathieu was an enthusiastic young man, passionate, very endearing, and extremely appreciated for his kindness and politeness.”
