Rafael Nadal has criticised the decision to ban Russian and Belarusian players from Wimbledon as a response to the Russian invasion of Ukraine.
Players from Russia and Belarus have also been barred from any of the UK grass-court tournaments by the All England Lawn Tennis Club (AELTC).
"I think it's very unfair [on] my Russian tennis mates, my colleagues," said Spaniard Nadal.
"It's not their fault what's happening in this moment with the war."
Serbia's Novak Djokovic has called the ban "crazy", while Russian world number eight Andrey Rublev said the ban was "complete discrimination" and "illogical".
