Daniil Medvedev is the latest entry in the group of players who are facing injury concerns ahead of the upcoming French Open.
The world number four retired from the Madrid Open quarter-finals on Thursday due to an injury to the upper part of his right leg
The 28-year-old had treatment while leading Czech Jiri Lehecka 3-2 in the first set and again two games later. He lost the set 6-4 before informing the umpire about retiring from the match.
“It was a return when he served and volleyed and I don’t know if I felt it on the return or on the drop shot, but when I ran, I wanted to run faster and faster during the movement, and suddenly felt my hip blocked,” Medvedev said.
“I couldn’t sprint, like when you strain a muscle or have a spasm, which is tough to know which of the two. Working with the physio, I asked if I could make it worse. He said ‘if it’s a tear, then yes. If it’s a spasm, no’.
“I tried to play and my mind wasn’t letting me to go full. At the end of the set, I was (thinking) if I want to continue, I’ll just try to sprint to the net… When I sprinted I felt pain. So I was like: no need to continue.”
Earlier, Australian Open champion Jannik Sinner also withdrew before his quarter-final against Felix Auger Aliassime after suffering a hip injury.
World number three Carlos Alcaraz went down in the quarter-final to Andrey Rublev while managing a right forearm issue that had ruled him out of Monte Carlo and Barcelona.
Medvedev is also unsure about defending his Rome title next week.
“Hopefully for sure tomorrow or day after, because normally you need time, MRI to see what it is, and if it’s something five days, two weeks, I have no idea.”
The French Open starts on May 26.
