Liverpool's England striker Daniel Sturridge has had an operation on his injured hip.
Sturridge, who flew to the United States for assessment last week, revealed the news on social media and said the surgery was a success.
A message on his Instagram account read: "Just want to let the world know I've had a successful operation on my hip today and I want to thank God for allowing that to be possible.
"Onwards and upwards from here. Thanks for the support. Daniel."
Injuries have restricted Sturridge to just 18 appearances this season, and he previously spent time in the States for treatment on a long-term thigh problem.
The 25-year-old did not say how long he expected to be out following the hip surgery, but the aim of his latest trip to Boston was to find a long-term solution to his persistent injury problems.
Speaking last week Liverpool manager Brendan Rodgers said: "I think we have found some underlying issues that maybe relate to Daniel's issues and problems this season and the ongoing problems he's had.
“The medical team here, liaising with some of the medics in America, are doing everything we possibly can to give Daniel every opportunity to stay consistently fit and available.”
