French Open champion Simona Halep has withdrawn from next week’s Nature Valley International in Eastbourne because of an Achilles problem.

The world number one won an emotional first grand slam title at Roland Garros earlier this month but will go into Wimbledon without an official match on grass.

Halep wrote on Twitter: “I’m very sorry to announce that I’m withdrawing from next week’s Nature Valley International.

“I was experiencing Achilles tendon pain and inflammation during the French Open and it has yet to fully recover. I’ve been advised by my doctors that it needs more rest while continuing treatment. I loved competing at Eastbourne last year and hope to see you at this wonderful event next year.”

Halep’s withdrawal leaves four top-10 players in the field, including last year’s champion Karolina Pliskova and runner-up Caroline Wozniacki.
