Bayern Munich face anxious wait on Klassiker injuries to Ismael Saibari, Serge Gnabry and Michael Olise

Saibari left on crutches after a collision with Kobel; Gnabry and Olise also departed with apparent muscle injuries during the 1-1 draw.

Bayern Munich suffered a frustrating evening on the injury front during Saturday's Der Klassiker against Borussia Dortmund at the Allianz Arena, which ended 1-1.

Ismael Saibari and Serge Gnabry were both forced off in the first half within three minutes of each other. Saibari came off worse in a challenge with Dortmund goalkeeper Gregor Kobel and was seen leaving the stadium on crutches. Gnabry and Michael Olise, who departed late in the match, both appeared to go to ground off the ball with muscle injuries.

Bayern CEO Jan-Christian Dreesen said afterwards: "I can't yet say exactly how serious their injuries are." The Bundesliga champions took the lead twice through Konrad Laimer and Dayot Upamecano, but Borussia Dortmund salvaged a draw with goals from Serhou Guirassy and Fabio Silva. Ballon d'Or winner Harry Kane also missed a second-half penalty when Bayern led 1-0.
