Cameroon international Patrick Ekeng has died after collapsing during a match for his club Dinamo Bucharest.
The 26-year-old came on as a 63rd minute substitute but collapsed just seven minutes later.
Paramedics attempted to resuscitate him but he was pronounced dead at Floreasca Emergency Hospital less than two hours later.
He was just 26.
Local media in Romania, where the match was being screened live on television, said Ekeng suffered a fatal heart attack.
Ekeng only joined Dinamo in January and was making just his seventh appearance for the club when he collapsed in the Romanian league match against Viitorul Constanta, which Dinamo were winning 3-2.
