Nadal was forced to skip the French Open for the first time in over two decades after admitting that his team had been unable to find a solution to the problem.
The Spaniard, who turns 37 on Saturday, revealed last month that he will take a vacation, maybe for the rest of the season, before embarking on a farewell tour next year.
Nadal’s reps confirmed the surgery on Friday, with the 14-time French Open winner getting an arthroscopic examination of his left psoas muscle in Barcelona.
The results will be released on Saturday morning.
