Fan draped in Ukrainian flag asked to leave following a complaint from a Russian player

At the Western & Southern Open, the chair umpire asked a fan with a Ukrainian to either remove the flag or leave following a complaint by a Russian player. The official reason cited was due to the flag being too large, but that rule is seldom enforced strictly.

The official statement from the organizers read as follows:

"Per the Western & Southern Open's bag policy, as stated on the tournament's website, flags or banners larger than 18 x 18 are prohibited. Therefore, the patron was asked to remove the flag from the grounds and after doing so was allowed to remain at the tournament. Any inquiries about the chair umpire should be directed to the WTA Tour."

The event took place during a women's singles qualifying match between Anna Kalinskaya and Anastasia Potapova.
