Charlton Athletic striker Yann Kermorgant could be out for as long as three months after breaking his ankle.
The 30-year-old Frenchman sustained the injury in training last week and will need to undergo an operation.
Physio Erol Umut said: "We were not happy with the outcome of his X-ray after he had a collision in training.
"We had a further scan that revealed the fracture. He will be operated on this week and it will potentially rule him out for three months."
Kermorgant, who joined the Addicks on a free transfer last year, has scored two goals in six appearances this season.
