Former world number one Serena Williams hinted on Thursday that she could make her long-awaited return at Wimbledon in June, exactly a year since she last played on the tour at the same Grand Slam.

Williams, 40, limped out of last year's first-round match at Wimbledon in tears due to a leg injury.

She also skipped the Olympics in Tokyo and the U.S. Open in 2021 due to the hamstring injury, as well as the Australian Open earlier this year.

On an Instagram story with NFL quarterback Aaron Rodgers, Serena said: "We've been talking about my comeback and he's been hyping me up and getting me ready for Wimbledon. Can't wait!"

When Rodgers asked her about a potential comeback at the U.S. Open, she added: "Wimbledon's before the U.S. Open, I've got to play Wimbledon first. Exciting!"

Wimbledon runs from June 27-July 10. Williams has won the grasscourt major seven times, with her last success coming in 2016.

Earlier on Thursday, her long-time coach Patrick Mouratoglou revealed he was now working full-time with twice Grand Slam champion Simona Halep after speaking to Williams. 

Williams, who has been on the hunt for an elusive 24th major since winning her last Grand Slam title at the 2017 Australian Open, has slipped to 246th in the women's rankings.

She reached the final in four Grand Slams since giving birth to daughter Olympia in 2017 but lost in straight sets on each occasion.
