The 14th-ranked Canadian, 22, had recently hit form on the European clay. Shapovalov pushed 13-time French Open champion Rafael Nadal all the way in the third round in Rome, holding two match points, and he backed that up by reaching the final of the Geneva Open on Saturday.

But, after losing to Casper Ruud, Shapovalov underwent tests on a sore shoulder and has decided not to play in the year's second grand slam, which starts on Sunday, DPA reports.

Shapovalov tweeted: "I'm saddened to share that after consulting with my medical team I've made the difficult decision to withdrawal from @rolandgarros. Unfortunately my shoulder has been bothering me and while medical tests look good, it is for the best to rest. See you in 2022, Roland-Garros."

Shapovalov has played in the main draw at Roland Garros three times, with his best performances coming in 2018 and 2020, when he reached the second round.
