Senegal have been criticised after Sadio Mane continued playing despite suffering suspected concussion in a "sickening collision" with Cape Verde goalkeeper Vozinha.
Mane remained on the pitch for several minutes despite appearing to sustain a head injury in the incident during Tuesday's Africa Cup of Nations match .
The Liverpool striker scored before eventually being substituted.
Brain injury association Headway said Mane's health had been put at risk.
"On the face of it, this seems to be yet another example of football putting results ahead of player safety," said Luke Griggs, deputy chief executive of Headway.
