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.

Grigor Dimitrov suffered a truly shocking injury while he was playing his round of 16 match at Wimbledon against Jannik Sinner. The Bulgarian veteran was unleashing one of the best performances of his entire career and was in full control of the match, despite the fact that the world number 1 was on the other side of the net.
