Berlin: Borussia Dortmund’s Maximilian Philipp will face a lengthy spell on the sidelines after suffering a serious knee injury, the Bundesliga club said.

The 23-year-old striker fell on his knee and had to be carted off the pitch early in the game against Bayer Leverkusen, which ended in a 1-1 stalemate.

Philipp was replaced by Andre Schuerrle and will be out of action for “several months”. According to the club’s statement on Tuesday, the summer signing suffered a serious injury to his kneecap.

The striker joined from Freiburg in the summer 2017 to score six goals in 11 appearances.

Struggling Dortmund, who have not won since October 28 in all competitions, sit sixth in the Bundesliga standings. They clash with bottom side Werder Bremen on Saturday.
