Italy's Matteo Arnaldi says withdrawing from his first Grand Slam semi-final through illness is an experience he would "not wish on anybody".
Arnaldi, 25, was due to play his close friend Flavio Cobolli in the French Open last four on Friday, but pulled out shortly before the match because of a virus.
The announcement was made at about 17:35 BST, 25 minutes before the Italian pair were due to walk out on court in Paris.
"I tried to see if I could get on court but every time I get up I feel dizzy. It was the right decision to take," said 104th-ranked Arnaldi, who had never previously gone past the fourth round of a major.
"I just know I can't move, I can't eat and I can't drink - there was no way I was able to play."
