Former Liverpool defender Rigobert Song, 40, the ex-captain of Cameroon's national side, was in a coma Monday after suffering a stroke.
Cameroon's state radio reported that Song, who also played for West Ham United, Metz and Lens in France and Galatasaray in Turkey, was rushed to a nearby hospital from his Yaounde home on Sunday after suffering a cerebral aneurysm.
Song was in a coma, the radio reported.
"I wish you lots of courage and a speedy recovery," former Cameroon team-mate Samuel Eto'o said in a Facebook post.
Song, capped 137 times, played in four World Cup finals and a record eight African Nations Cups as well as winning Olympic gold in 2000.
