Carlos Alcaraz informed his fans on Instagram Friday that he suffered an upper leg injury during his run at the US Open.

The #NextGenATP Spaniard visited Dr. Juanjo López after retiring during his quarter-final match against Felix Auger-Aliassime. That visit revealed a fibrillar tear in his vastus medialis and lateral quadriceps as well as an elongation in his adductor.

“I have to rest for a few weeks and recover in order to reach Indian Wells with the best level,” Alcaraz wrote. “Thank you very much for the support!”

The 18-year-old made history in New York, where he became the youngest player in the Open Era to reach the US Open quarter-finals. The highlight of his run came in the third round, in which he stunned third seed Stefanos Tsitsipas in a five-set thriller.
