Two-time grand slam champion Victoria Azarenka was dropped from a pre-U.S. Open exhibition match that will raise money for humanitarian assistance in Ukraine.

The former No. 1 ranked player in the world is from Belarus, who assisted Russia in their invasion of Ukraine earlier this year.

Marta Kostyuk, a player from Ukraine, declined an invite to participate due to Azarenka originally being scheduled to play.

"When we found out that there would be representatives of Russia or Belarus at this event, I immediately said that I will not participate in this," Kostyuk said, according to Tennis Up To Date.

Kostyuk also criticized Azarenka for her lack of support to her personally, as well as the people of Ukraine.

"I did not understand the reason why they called Victoria Azarenka," she added. "There was no open help from her in our direction. She did not communicate with me, but I know that she communicated with Serhiy Stakhovsky, with Gael Monfils in Madrid. There was no dialogue with me personally, although it cannot be said that I was invisible. Maybe I'm not that visible because I'm not ranked high enough to be talked to, but that's not what I'm talking about, I'm talking about the fact that I've been active enough since the beginning of the war."

VICTORIA AZARENKA, TENNIS STAR FROM BELARUS, 'DEVASTATED' BY ATTACKS ON UKRAINE

"In the last 24 hours, after careful consideration and dialogue with all parties involved, Victoria Azarenka will not be participating... this evening," the USTA said in a statement. "Vika is a strong player leader and we appreciate her willingness to participate. Given the sensitivities to Ukrainian players, and the ongoing conflict, we believe this is the right course of action for us."

Azarenka, along with all other plays representing Russia or Belarus, were banned from playing in Wimbledon earlier this summer.
