Toulouse goalkeeper Yohann Pele has been ruled out for at least six months because of a blockage in his lung.
The 27-year-old has been diagnosed with a bilateral pulmonary embolism after being hospitalised on Tuesday morning.
A statement on the club's website said: "Toulouse goalkeeper Yohann Pele has suffered a bilateral pulmonary embolism. His unavailability is a minimum of six months. All at TFC wish the player a speedy recovery a lot of courage."
Pele has been plagued by injury and health problems since joining Toulouse from from Le Mans before the start of last season.
He suffered a hand injury and a ruptured posterior ligament, before suffering from phlebitis, a vein inflammation which can lead to a pulmonary embolism, in the summer.
