Bayern Munich have provided further details on the injuries Ismael Saibari and Serge Gnabry sustained against Borussia Dortmund.

Ismael Saibari and Serge Gnabry were both forced off in the first half of Bayern Munich’s 2-2 draw with Borussia Dortmund in the Bundesliga on Saturday.

On Sunday, the German champions confirmed that Saibari has undergone surgery after tearing the syndesmotic ligament in his right ankle.

According to Bild, Saibari is expected to be sidelined for at least three months.

Gnabry, meanwhile, sustained a muscular injury to his left hamstring, with Bild reporting that he is expected to be out for four to six weeks.

Bayern have yet to provide an update on Michael Olise, who was forced off in the second half.

According to Bild, Bayern hope to have Olise available for Tuesday’s Champions League encounter with Atletico Madrid, but it's unclear if he will recover in time.
