US Open fans were dealt a major blow on Tuesday evening as Marketa Vondrousova withdrew just two hours before her quarterfinal matchup against Aryna Sabalenka.
The news, first reported on ESPN, is reflected on the US Open website, which shows Sabalenka winning via walkover.
Fans had paid extremely exorbitant prices to see Tuesday's night session on Arthur Ashe, as resale tickets were starting at $500 - and going up to $2,000 for courtside seats - just hours before the match was scheduled to begin at 7pm.
Vondrousova, the 2023 Wimbledon champion, has battled injuries in the past and reportedly picked up a new injury in practice.
She is said to have practiced for just 10 minutes after stepping onto the court at 4pm and was seen crying on the bench.
Sabalenka will now face American Jessica Pegula in the semifinals - in a rematch of their championship matchup last year.
The Belarusian took to her Instagram story to react to the unfortunate news, writing: 'So sorry for Marketa after all she's been through. She has been playing amazing tennis and I know how badly this must hurt for her.
'Take care of yourself and I hope you can recover quickly.'
