Cameroon midfielder, Patrick Ekeng, died on Friday after collapsing on the pitch during a match for Dinamo Bucharest.
Ekeng fell to the ground shortly after coming on as a 62nd minute substitute during a league match against Viitorul Constanta.
Media reports said he suffered suspected heart attack and was pronounced dead in hospital two hours later.
Dinamo have confirmed the death of Ekeng.
A statement on the club’s official website reads: “Dinamo lost tonight, forever, footballer Patrick Claude Ekeng.
“On behalf of everyone at Dinamo, sincere condolences to the bereaved family. God rest his soul.”
The Cameroon FA also confirmed the news on Twitter, while Ekeng’s former club Cordoba tweeted: “There are no words to express our sorrow for the death of Patrick Ekeng.”
The 26-year-old Cameroon international joined Dinamo in January, but had previously donned the colours of Le Mans and Lausanne in France and Switzerland respectively.
His death is another loss for the Indomitable Lions, fellow Cameroon international, Marc-Vivien Foe, died after collapsing during a 2003 FIFA Confederations Cup semi final against Columbia at the Stade de Gerland in Lyon, France.
Tragedy was averted in 2012, when Bolton Wanderers player, Fabrice Muamba, collapsed during an FA Cup game at Tottenham, but recovered after urgent medical attention.
Ekeng made his debut for Cameroon in January 2015 and was named in the squad for the 2015 Africa Cup of Nations where Cameroon was eliminated in the group stage.
