Alexander Zverev suffered torn ligaments during the French Open semi-final against Rafael Nadal on Friday.
Zverev rolled his ankle and was forced to retire against 13-time champion Nadal.
“Based on the first medical checks, it looks like I have torn several lateral ligaments in my right foot,” the German wrote on Instagram on Saturday.
“I will be flying to Germany on Monday to make further examinations and to determine the best and quickest way for me to recover.”

World No 3 Zverev, who was gunning for his first Grand Slam title, would have taken the top spot in rankings if he had won the French Open.
He was 7-6, 6-6 down when he took the tumble that ended what had looked like becoming a memorable contest.
He said on Friday he was concerned the injury, which caused him to scream in pain on court Philippe Chatrier, was “very serious”.
Meanwhile Nadal, who celebrated his 36th birthday on Friday, will take on Casper Ruud in Sunday’s final.
