Zverev was Ferrer's last opponent on tour. He beat the Spaniard in the second round in Madrid last year in Ferrer's final tournament before retirement. Zverev added that he has pulled out of next week's exhibition series of tournaments in Berlin. Zverev was one of the players who faced public criticism for their involvement in Novak Djokovic's Adria Tour series, after which four players including Djokovic tested positive for the coronavirus.
“I have made the decision to stay put and train with my team and not play any organized events at the moment,” Zverev wrote. “It's never nice to miss the chance to play at home, but I will be back soon.”
Zverev said Wednesday he has tested negative three times for the coronavirus.
