Sadio Mane suffered a head injury then scored to help send Senegal to the Afcon quarter-finals, but was then substituted and taken to hospital.
Mane fired home from a set-piece after 62 minutes in a 2-0 win over Cape Verde, but had been hurt earlier in a nasty clash of heads with goalkeeper Vozinha, who was sent off for the incident.
Liverpool forward Mane then left the field shortly afterwards complaining of a headache and was taken to hospital.
Later on Tuesday, both Mane and Vozinha were pictured together smiling and giving the thumbs up from hospital.
Senegal head coach Aliou Cisse said of Mane’s condition after the win: “I don’t know, but I hope he is ok, he is in hospital now, we will see.
“I have no news from the doctors, I hope there is nothing serious, but in any case I can’t give any information on Sadio.
“He had a shock with the goalkeeper, he didn’t feel well, his head felt dizzy so he left [the pitch].”
Substitute Bamba Dieng scored Senegal’s second goal deep in stoppage time against a gallant Cape Verde side, who also had Patrick Andrade sent off after 20 minutes.
It remains to be seen whether Mane will be able to feature for the Lions of Teranga in the quarter-final on Sunday against either Mali or Equatorial Guinea.
Mane had struck the woodwork in the opening minutes but it proved a false dawn as Senegal laboured through the first half, as they had done in the group phase where they finished top of the standings despite scoring once. —Sky Sports
