Roger Federer withdrew from his Italy Open quarter-final against Stefanos Tsitsipas due to an injury to his right leg, organizers said Friday.
The 37-year-old Swiss, who returned to play in the European clay season after two years, won consecutive matches against Joao Sousa and Borna Coric to reach the quarter-finals of the Roman tournament on Thursday.
“Unfortunately, King Roger had to withdraw from the tournament due to an injury to his right leg,” the organizers wrote on Twitter. “We wish him a speedy recovery. Thank you for the incredible emotions.
The injury sows doubts about his preparation for Roland Garros, which begins at the end of this month, as it will only arrive with five matches in brick dust to the second Grand Slam of the year.
