Stoke City full-back Junior Tchamadeu saw his first Africa Cup of Nations campaign with Cameroon end in painful fashion.
The 22-year-old was carried off on a stretcher with a knee injury after just 24 minutes of their quarter-final defeat by the hosts Morocco in Rabat.
Tchamadeu, who scored his first senior international goal in a 2-1 win over South Africa earlier in the competition, was injured after Morocco's Manchester United defender Noussair Mazraoui accidentally landed on his knee following a challenge.
Morocco won the game 2-0 and will now face either Algeria or Nigeria in the semi-finals on Wednesday, 14 January (20:00 GMT).
