Impact on tennis: Jannik Sinner will not play for the rest of the year due to injury, and another star will be number 1 for the first time.

Jannik Sinner has announced the premature end of his 2026 tennis season to continue treatment for an injury to his right knee. The decision rules him out for all remaining tournaments on the calendar.

His absence from the remainder of the season creates a significant shift at the top of the sport, opening the path for Alexander Zverev to become the world number one for the first time in his career.
