Alexander Zverev has reported that initial medical checks indicate that he has torn several lateral ligaments in his right foot following his sickening injury at Roland Garros Friday.

The 25-year-old German was more than three hours into an epic semi-final with Rafael Nadal when he badly rolled his ankle while moving to his right. The World No. 3 crashed to the ground and was taken off court in a wheelchair before returning several minutes later to shake the hand of the chair umpire and hug Nadal.

“I am now on my way back home,” the World No. 3 wrote on Instagram. “Based on the first medical checks, it looks like I have torn several lateral ligaments in my right foot.

“I will be flying to Germany to determine the best and quickest way for me to recover. I want to thank everyone all over the world for the kind messages that I have received since yesterday.”

Zverev and Nadal had enthralled fans on Court Philippe Chatrier for three hours and 13 minutes before Zverev’s injury brought the match to a jarring conclusion on the eve of the second-set tie-break. Nadal had rallied from 2/6 in the first set tie-break to hold a 7-6(8), 6-6 lead at the time.

Zverev was chasing his first Grand Slam title and the No. 1 Pepperstone ATP Ranking, which he would have claimed for the first time by winning the title.
