wenty-time Grand Slam champion Roger Federer and British number one Johanna Konta have both pulled out of this summer's Tokyo Olympics.
Federer, 39, has suffered a setback with an existing knee injury.
Konta, 30, has contracted Covid after withdrawing from Wimbledon when a member of her team tested positive and she was identified as a close contact.
The Swiss legend won doubles gold at Beijing 2008 and silver in 2012, losing the singles final to Andy Murray.
Federer, now ranked number nine in the world, had two knee surgeries in 2020.
Team GB is not able to name a replacement for Konta, as no other British players are ranked highly enough to qualify, so her withdrawal deprives Heather Watson of a doubles partner.
The British number two will be limited to singles unless she and Joe Salisbury make the cut for the mixed doubles. The entry list will be confirmed once the Games are underway.
Dan Evans, Andy Murray and the Wimbledon mixed doubles champion Neal Skupski complete the GB team for the tennis, which starts on 24 July.
If it's like normal there's no chance Watson and Salisbury make cut for mixed, as the cutoff is norm super high with everyone wanting to play mixed.
But with everyone withdrawing who knows. The situation for this Olympics clearly isn't helping, it's ok for most sports where the Olympics is everything, but the tennis players going into this bubble have got to be at their best just a few weeks later on the other side of the Pacific. On top of that the US events have an effective carrot as there are minimal restrictions on players in them.

British number one Dan Evans has pulled out of the Tokyo Olympic Games after testing positive for Covid-19.

On Tuesday, Britain's top female player Johanna Konta also withdrew from this summer's Olympics as a result of contracting coronavirus.
The Games takes place from 23 July until 8 August.
Evans, who is ranked 28th in the world, said he was unable to prepare properly and get ready for what would have been his maiden Olympics in Tokyo.
He posted on Instagram: "I want to wish the entire GB team all the very best for the games and look forward to being back on the court in the near future."
