Aston Villa defender Jordan Amavi has picked up a potentially serious injury while on international duty.
Amavi went down in clear pain clutching his knee in the 70th minute of an under-21 game against Northern Ireland, being held in France.
The Frenchman had to be helped off the pitch and looked in clear pain, grimacing with his injured leg raised off the ground.
French newspaper L'Equipe report Amavi has been taken to the local Saint-Brieuc Hospital to be assessed.
His international coach Pierre Mankowski expressed worry for the former Nice left-back.
He said: "Our doctor and that of Guingamp are trying to look after him. According to the first information available that it would be a knee sprain. It is not yet known whether the ligament is ruptured. It's too early to say."
L'Equipe added that: "His cry echoed in the stadium of Roudourou... the images have raised fears of a consequent downtime."
Aston Villa have had an awful start to the season, winning just five points, and they currently sit bottom of the league.
Losing Amavi, who has been one of their best players, would be a terrible blow. The next man up at left-back would be Kieran Richardson, who was an underwhelming performer for much of last year.
