Dinamo Bucharest and Cameroon midfielder Patrick Ekeng has died aged 26 of a suspected heart attack after collapsing on the pitch.
BBC Sport reports that Ekeng fell to the floor in the 70th minute of a televised Romanian league match between Dinamo and Viitorul.
He was pronounced dead in hospital two hours later.
Ekeng's former club Cordoba tweeted: "We have no words to express our sadness at the loss of Patrick Ekeng. We mourn your loss."
Ekeng had also previously played for Le Mans and Lausanne.
In 2003, Cameroon international midfielder Marc-Vivien Foe died after collapsing during a Confederations Cup match against Colombia in France.
