Cameroonian international footballer Patrick Ekeng has died after collapsing on the pitch during a match, his club Dinamo Bucharest confirmed.
The 26-year-old midfielder reportedly collapsed without any player making contact with him, just seven minutes after coming onto the field.
He had been brought on as a substitute during a league match against Viitorul Constanta.
"Resuscitation attempts were made for an hour and half without success," the AFP news agency reported Liviu Paltinean, the team doctor, as saying.
Ekeng was taken to hospital but could not be resuscitated.
Fans of the team gathered outside the hospital late in the evening in tribute to the player.
