Russian player Veronika Kudermetova, who is sponsored by one of the country's oil and gas giants Tatneft, says she will be able to play at Wimbledon by removing the company's logo from her kit.
The All England Club (AELTC) will allow Russians and Belarusians to compete this year as neutrals, if they agree not to show any public support for the invasion of Ukraine.
But the conditions also prohibit players receiving funding from either state.
This includes "sponsorship from companies operated or controlled by the state" - but only "in relation to their participation in The Championships".
