Former world number one Venus Williams will make her singles comeback after nearly a year at the Citi Open in Washington, DC that begins next week, organizers said on Thursday.

The seven-time Grand Slam champion accepted a wildcard for the July 30-Aug 7 WTA 250 event a day after announcing she will also compete at next month's WTA 1000 event in Toronto, where she will be joined by her sister Serena. 

Venus, 42, last played a singles match at the Chicago Women's Open in August 2021, losing in the first round to Hsieh Su-wei.
