Paris (AFP) - Rafael Nadal reached his 14th French Open final on Friday after Alexander Zverev was forced to quit their semi-final after suffering a horror right ankle injury.
Zverev had to leave the court in a wheelchair after turning his ankle trailing 7-6 (10/8), 6-6 after more than three hours of play.
After screaming in anguish, a tearful Zverev was helped from the court by medics.
Minutes later, the 25-year-old returned to the court on crutches and conceded the match.
"It's very tough and very sad for him.He was playing an unbelievable tournament and he's a very good colleague on the tour," said Nadal.
"I know how much he's fighting to win a Grand Slam.For the moment, he was very unlucky.I'm sure he'll win not one, but much more than one.I wish him all the best.
"It had been a super tough match.Over three hours and we didn't even finish the second set.It's one of the biggest challenges on the tour when he's playing like he did today."
He added: "For me, to be in the final of Roland Garros is a dream, without a doubt, but at the same time, for it to finish that way...I have been there in the small room with Sascha and to see him crying like that -- I wish him all the best."
Nadal, chasing a record-extending 22nd Grand Slam title, will play either Marin Cilic or Casper Ruud in Sunday's final.
