World No.1 Jannik Sinner admitted he was concerned about his elbow injury after reaching the quarter-finals at Wimbledon thanks to the withdrawal of Grigor Dimitrov

Jannik Sinner has advanced to the Wimbledon quarterfinals despite hurting his right elbow on a fall and dropping the first two sets, because his opponent, Grigor Dimitrov, had to quit with an injured pectoral muscle.

Jannik Sinner is through to the Wimbledon quarterfinals, though not in the way he wanted. Sinner lost the first two sets of his fourth-round match with Grigor Dimitrov on Monday before Dimitrov was forced to retire from the match after suffering an apparent pectoral injury.
