Britain's Jack Draper will miss the grass-court season, including Wimbledon, with a shoulder injury.
Draper, 21, retired in the first round of his French Open senior debut against Argentina's Tomas Martin Etcheverry.
"It's clear my shoulder is going to need time and rehab to get back to where it needs to be," Draper wrote on Instagram.
"My team and I have made the difficult decision to miss the grass-court season this year."
He added: "I guess in this sport there are so many ups and downs but this one is tough to take.
