Real Madrid's French forward Kylian Mbappe (25) has been diagnosed with an injury to his left thigh, the LaLiga club said on Thursday, making him a doubt for next week's FIFA Intercontinental Cup final.
Mbappe was replaced during the first half of Real's 3-2 win at Atalanta in the Champions League on Tuesday, having given his side the lead with a 10th minute goal.
Real manager Carlo Ancelotti said afterwards that Mbappe had suffered an overload, an ischial (lower pelvis) discomfort, adding that he did not believe it to be a serious injury but would need to wait for the player to be examined.
Mbappe, who also scored in last weekend's 3-0 win over Girona, looks set to miss Real's league game at Rayo Vallecano on Saturday, and faces a race to be fit for the Intercontinental Cup final next Wednesday in Qatar.
Real will face either Mexico's Pachuca or Egypt's Al Ahly, who meet on Saturday.
