The tennis star has been summonsed to face the ACT Magistrates Court on August 2.

"(Police) can confirm a 27-year-old Watson man is scheduled to face the ACT Magistrates court ... in relation to one charge of common assault following an incident in December 2021," ACT Police said in a statement on Tuesday.

The Canberra Times newspaper reports that the assault allegedly involved a former girlfriend.

Lawyer Jason Moffett confirmed he had been briefed in the matter and his client, Kyrgios, was aware of the allegation.

"It's in the context of a domestic relationship," Mr Moffett told The Canberra Times.

"The nature of the allegation is serious, and Mr Kyrgios takes the allegation very seriously.

"Given the matter is before the court ... he doesn't have a comment at this stage, but in the fullness of time we'll issue a media release."

Kyrgios is due to play Chile's Cristian Garin at the All England Club on Wednesday for a place in the Wimbledon semi-finals.

It will be the one-time world No.13's third chance to make a grand slam semi-final for the first time in his tumultuous career.
