Newcastle United midfielder Yohan Cabaye fears that he may have sustained ligament damage to his left ankle while on international duty for France.
The 25-year-old was substituted during France's Euro 2012 qualifying win against Albania on Friday.
"It was a big pain, and I fear ligaments could have been damaged," he told L'Equipe.
"I will have tests, I don't know whether it is a sprain or a bad bruise but it was very painful and I couldn't carry on like that."
Cabaye moved to St. James's Park over the summer from Lille for an undisclosed fee.
