World No. 1 Daniil Medvedev may not be able to play at Wimbledon this year due to his home country being involved in the war with the Ukraine.

Wimbledon authorities are believed to be considering a blanket ban on all Russian tennis players from this year’s Grand Slam tournament unless they provide assurances that they don’t support the Putin regime.

The UK sports minister Nigel Huddleston has said he is in discussion with the All England Club on the issue and was quoted in Parliament in London on the matter.

“I don’t think people would accept [athletes] very clearly flying the Russian flag in particular if there’s any element of support for Putin and his regime… We are looking at the mechanics of how we could work on that for individuals,” he said.
