It's been a stop-start comeback for since he returned from a two-year injury layoff in January. The former Wimbledon finalist has played just four tournaments and his last match was more than a month ago in Miami.

The Australian has now teased his return to the tennis court, hinting that he could make his comeback at the French Open for the first time in eight years. Kyrgios notoriously has a love-hate relationship with the clay and has avoided Roland Garros throughout his career but he is now preparing to head to Paris.

Kyrgios notched his first match win in two-and-a-half years at the recent Miami Open, . But he has not played since losing to Karen Khachanov a couple of days later.

The former world No. 13 has given few updates on his progress since crashing out in the second round. But, after celebrating his 30th birthday, he took to social media to confirm that he was back in training.

"Hey guys. Couple days after my birthday now. Just getting into training and getting ready to head to Paris in about three weeks," he said.

"I just want to say, I appreciate all the birthday messages. It's almost been impossible to get back to every single one of you. But I really appreciate the love, the support from all my fans.

"Family and friends that I'm yet to reply to, I'm doing my absolute best. But I really felt the love.

"The big three-zero. Time is moving but I definitely felt special. So take it easy, thank you to everyone and I'll do the best I can to get back to you."

Kyrgios also shared a photo in the gym, where he's been putting in the work to return to the tennis court.

The 30-year-old's Parisian travel plans line up with the French Open, which begins on May 25.

However, Kyrgios' name did not appear on the French Open entry list when it was released earlier this month. The Aussie has a protected ranking of No. 21, which would have secured him a spot in the Roland Garros draw.

He could still receive a wildcard, as French Open organisers give one reciprocal place to an Australian in return for the Australian Open granting a wildcard to a French player.

The former world No. 13 has only competed in the tournament five times in his career from 2013 to 2017 and never made it to the second week.

Kyrgios could also be jetting to Paris for punditry duties. During his lengthy injury absence, he started working with the BBC, ESPN, Eurosport and Tennis Channel, commentating on matches at several tournaments, including Wimbledon.
