Tours midfielder Thomas Rodriguez has died at age 18, the French club announced on Friday.
Rodriguez died overnight from Thursday to Friday. No details were given as to the cause of death.
"Tours FC is devastated by this drama, which plunges the club into an immense sadness," the Ligue 2 side's statement said.
Rodriguez joined in 2016 and progressed through the Tours youth academy before playing for the reserves.
"His footballing qualities, his drive and his motivation made him a player promised a bright future as a professional," the statement said. "The club offers its most sincere condolences to his family, his loved ones, and all the teammates and friends of Thomas."
Tours' game against Valenciennes scheduled for later on Friday was postponed. A minute's silence will be held at all stadiums in Ligues 1 and 2 this weekend.
Rodriguez's death comes after Fiorentina captain Davide Astori was found dead in his hotel room on Sunday after a suspected cardiac arrest before an Italian match at Udinese.
In January 2009, 23-year-old Clement Pinault, a defender with Clermont in Ligue 2, died in hospital four days after suffering a heart attack at home.
