The Cameroon Football Federation (Fecafoot) has announced the death of Jeanine Christelle Djomnang on Sunday.
The 26-year-old goalkeeper collapsed during her warm-up before a Femina Stars Ebolowa match in southern Cameroon, and was rushed to hospital, the BBC reports.
Fecafoot said initial reports suggested that she died of a heart attack but it is now awaiting formal medical report.
The news came less than 48 hours after the death of Cameroon international Patrick Ekeng in Romania.
Djomnang complained of chest pains as she prepared to take on Louves MINPROFF Yaounde in the Cameroon elite league and died on her way to hospital.
A condolence book has been opened at the federation headquarters for both Ekeng and Djomanang
