It was a heartbreaking scene at Wimbledon on Monday evening after Bulgarian tennis player Grigor Dimitrov was forced to retire from his fourth-round match vs. world No. 1 Jannik Sinner despite leading the Italian superstar by two sets.
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.
