Jannik Sinner withdraws from multiple tournaments, raising concerns

World number one Jannik Sinner has not played since winning the Wimbledon final in July due to a knee injury. He has withdrawn from several tournaments, including the Canadian Open, Cincinnati Open, US Open, China Open, and Shanghai Masters. Adriano Panatta has expressed concerns about Sinner's situation, emphasizing the complications surrounding his knee problem. Sinner is scheduled to participate in the Six Kings Slam exhibition event in Saudi Arabia later this month, followed by three title defenses in Vienna, Paris, and the ATP Finals. His continued absence may impact his ranking as Alexander Zverev closes in on him.
