Atletico Madrid striker Antoine Griezmann is reportedly expected to miss next weekend's La Liga showdown with rivals Real Madrid after picking up an ankle injury.
The 25-year-old hobbled off during France's World Cup qualifying clash with Sweden on Friday night and is understood to have severely swollen his foot.
Spanish publication Marca claims that Atletico's medical chief has received a report that confirms the club's worst fears, with their key forward player facing at least a week on the sidelines.
Griezmann has started in all 10 of the Rojiblancos' league games this term, scoring six goals and setting up a further four, but Diego Simeone will likely now have to make do without his attacking ace for the visit of Madrid to the Vicente Calderon on Saturday evening.
France, who recovered from a goal down to beat Sweden 2-1 at the Stade de France, return to action on Tuesday with a friendly against the Ivory Coast.
