Italy’s Jannik Sinner gives a press conference after being defeated by Argentina’s Juan Manuel Cerundolo in their men’s singles match on day 5 of the French Open tennis tournament on Court Philippe-Chatrier at the Roland-Garros Complex in Paris on May 28, 2026. <\/p>\n
World No. 1 Jannik Sinner is dealing with an undisclosed illness\/injury that could keep him off the court for the foreseeable future.<\/p>\n
According to Italian outlet La Gazzetta dello Sport<\/a>, Sinner underwent two days of tests at San Raffaele Hospital in Milan on Monday and Tuesday \u2014 to investigate the causes of his physical collapse<\/a> in his second-round loss at the French Open. After going up 5-1 in the third set against Juan Manuel Cerundolo, the Italian shockingly dropped 18 straight points before losing the match in five sets to the World No. 45 Argentinian.<\/p>\n The report noted that Sinner\u2019s illness is being kept \u201cstrictly confidential\u201d by his camp and the medical staff that treated him this week.<\/p>\n \u201cThe doctors\u2019 investigation is rightly kept strictly confidential, and San Raffaele has taken care to keep the file confidential so that no one might pry into his medical records and divulge confidential information,\u201d wrote Italian journalist Federica Cocchi.<\/p>\n Jannik Sinner Injury News Sparks Concerns<\/p>\n Cocchi\u2019s report added that \u201ccomprehensive investigations\u201d are underway to address Sinner\u2019s \u201cnumerous bouts of physical weakness\u201d dating back to the Australian Open earlier this year, where he risked an early exit due to cramps and dehydration.<\/p>\n \u201cIn January, in the scorching heat<\/a> of Melbourne, he risked an early exit from the tournament due to cramps and dehydration. Although resolved, this situation weakened him, leading to a semifinal defeat against Novak Djokovic that prevented him from retaining the 2025 title,\u201d the report highlighted.<\/p>\n Is Jannik Sinner Dealing With Cardiac-Related Issue?<\/p>\n La Gazzetta dello Sport noted that Sinner did not undergo medical tests at J Medical in Turin, as the hospital \u201clacks the equipment and expertise\u201d to carry out specific tests on the four-time major winner.<\/p>\n \u201cIn-depth cardiac and metabolic tests are being discussed to rule out any pathology or deficit,\u201d wrote Cocchi on Tuesday morning.<\/p>\n The one positive, however, is that Sinner seems to be in good spirits, and even smiled at the cameras when spotted leaving the hospital<\/a> in Milan on Monday.<\/p>\n \u201cHis spirits, however, are high. Yesterday afternoon, leaving the outpatients\u2019 wing of the Milanese hospital, he appeared smiling.\u201d<\/p>\n Sinner is still expected to defend his Wimbledon crown later this month, even though he will sit out upcoming grasscourt events at Stuttgart, Halle, Mallorca and Eastbourne in the lead up to the third major of the year. The Italian captured his first Wimbledon title last year<\/a> when he defeated Carlos Alcaraz in four sets. While he has yet to taste major success this year, Sinner has maintained a staggering singles record of 37-3, which includes title wins at Rome, Madrid, Monte-Carlo, Miami and Indian Wells. He was favored to win the French Open before his untimely collapse in the second round.<\/p>\n \n\t\t\tSai Mohan<\/a> covers the NBA for Heavy.com.
