The 32-year-old required treatment on his right knee during the 7-6 (7-2) 7-6 (7-2) win over his Russian opponent, while Federer made relatively light work of Hubert Hurkacz.
The old rivals have not played against each other since 2017, but Nadal has hinted that he could pull out of the semi-final if his knee has not sufficiently recovered.

‘But the desire to play a match like this against Federer is always very special, and it’s even more special if we’re both at a high level and at 100 percent.
‘Hopefully it will be that way, above all for me but also for the fans on site and for fans in general. I hope I will be able to play aggressively.
‘I need to be ready to react very quickly and to have everything in place to be able to succeed. If not, it will be very difficult.’

He explained: ‘I don’t think those matches matter that much, to be honest. A lot of time has gone by, unfortunately maybe for the rivalry, for us, or for me. It’s always better to keep on playing against him.
‘The fans are maybe more excited about us playing than me as I’ve always got to be focused on my own game. But it always brings extra energy into the stadium and for the both of us.’
