Watch: Alexander Zverev takes horrible tumble in French Open SF against Rafael Nadal, forced to retire and leave in a wheelchair

Rafael Nadal and Alexander Zverev were closing in on a second consecutive tie-break in their semifinal encounter at the 2022 French Open, before disaster struck the German.

On the last point of the 12th game in the second set, Zverev chased down a forehand struck by the Spaniard. The World No. 3 went for a routine slide, but his foot got caught in the clay, sending him tumbling. The fall was so bad that the German did not even attempt to hide his pain, screaming out in agony after hitting the ground.

The 25-year-old Zverev eventually managed to stand up after a long struggle but could barely take a step without assistance. The tournament organizers came to his aid, bringing out a wheelchair to escort the German off court so he could get the injury looked at by medical staff.

To his credit, Rafael Nadal rushed over to check on the World No. 3, even accompanying him to see the physio later. The Court Philippe-Chatrier crowd also acknowledged the German's efforts by giving him a standing ovation on his way out of the arena.

A few minutes later, Alexander Zverev reemerged, thankfully not in a wheelchair this time. However, the 25-year-old had to use crutches to make the short walk from the hallway to the chair umpire, where he officially conveyed that he would be withdrawing from the contest. Once again, he was greeted with a round of loud cheers from the audience.

It was expected, considering the nature of the fall. To put it into context, the fall was so bad that broadcasters initially refrained from showing a replay of the incident.

Nadal, meanwhile, moved on to the final, where he will attempt to lock up a record-extending 22nd Grand Slam and 14th French Open title.

Following his anticlimactic victory over Alexander Zverev, Rafael Nadal will lock horns with either Casper Ruud or Marin Cilic in the final of the 2022 French Open.

The 21-time Grand Slam champion holds the upper hand in head-to-head meetings with Cilic, leading 7-2. He has also won their last two matches. On clay, the pair have met only once before, at the 2011 Italian Open, where the Spaniard won in straight sets.

Nadal has never faced off against, who is being viewed as the favorite to reach Sunday's summit clash.
