Doctors rate Simona Halep as "50/50" for the French Open after suffering an ankle ligament injury in Rome, she has revealed.

WTA World No.4 Simona Halep has revealed she is "50/50" to compete at the French Open after suffering an ankle injury during the final of the Internazionali BNL d'Italia.

The Romanian wrote on social media that a scan showed she had torn a ligament  after falling against Elina Svitolina but she remains hopeful of a swift recovery. 

"Arriving early in Paris for treatment," said Halep. "The MRI scan shows a torn ligament from the fall in Roma. I'm keeping my fingers crossed for RG [Roland Garros] and will do everything possible to be ready.

"Doctors say it's 50/50 at the moment but it's made good improvement since Sunday."

She thanked tennis fans for their messages of support, adding: "We are remaining very positive."

Halep tripped and rolled her ankle at 5-2 in the first set, and later told reporters that she felt additional pain while hitting an inside-out forehand at 5-3 in the second set.
