World No. 1 tennis player Jannik Sinner has withdrawn from the Paris Olympics due to tonsillitis, a condition that inflames the tonsils and causes symptoms like sore throat and fever. Sinner, who won his first Grand Slam at the Australian Open this year, expressed his disappointment on social media, emphasizing the importance of representing Italy. His withdrawal leaves Novak Djokovic as the top seed, setting up potential high-stakes matches. Sinner's absence follows a series of health issues, including dizziness at Wimbledon and a hip injury earlier in the season. The Paris Olympics tennis tournament will take place at Roland Garros from July 27 to August 4.
