A statement reads: "German Cup winners Borussia Dortmund will be without Raphael Guerreiro for between three and four months. The 23-year-old underwent a foot operation today and is now set for a lengthy spell on the sidelines.
"Guerreiro sustained the injury while playing for European champions Portugal in a Confederations Cup group stage match against hosts Russia. BVB were subsequently assured by the Portuguese Football Association that the 23-year-old had only sustained a bruised foot.

"However, examinations conducted in Dortmund have now revealed that the foot of the Portugal international has suffered a clear break. Guerreiro, who made 35 appearances for Borussia Dortmund in the Bundesliga, the DFB Cup and the UEFA Champions League last season, scoring nine goals and setting up a further nine, will be out until October/November following the surgery."
Guerreiro scored six goals and contributed three assists in the Bundesliga last season after joining the club from French side Lorient, where he also had a good goalscoring record from left- back, managing 10 goals in 102 Ligue 1 appearances.
The news comes as a blow to Dortmund, who will be looking to mount a Bundesliga title bid next season after a disappointing league performance last term, finishing third and 18 points behind champions Bayern Munich.
