Borussia Dortmund’s Maximilian Philipp will face a lengthy spell at the sidelines after suffering a serious knee injury, the Bundesliga club confirmed in an official statement.

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, reports Xinhua news agency.

Philipp was replaced by Andre Schuerrle and will be out of action for “several months”.
