As Jannik Sinner pursues a fourth Grand Slam, he'll have somewhat of a physical limitation at Wimbledon. The Italian tennis star and world No. 1 is wearing a sleeve over his right arm for his quarterfinals matchup against Ben Shelton, a result of an injury he sustained in the last round.

Jannik Sinner has started his Wimbledon quarterfinal against Ben Shelton with a white arm sleeve over the right elbow he hurt in his previous match.

In a video of the moment, it looked as though the 34-year-old Dimitrov injured a pectoral muscle on a volley. Almost immediately after the hit, he fell to the ground, clutching the right side of his chest in pain.
