The 34-year-old Bulgarian won the first two sets 6-3, 7-5 and was tied with Sinner 2-2 in the third when he went down with the injury.

Jannik Sinner has been treated for a painful right elbow by a trainer at Wimbledon during a medical timeout in the second set while trailing in his fourth-round match against Grigor Dimitrov.

WADA accepted Sinner’s explanation that he was accidentally contaminated by a massage from his physiotherapist, who used a spray containing the banned substance to treat a finger cut. They ruled that Sinner ‘did not intend to cheat’ but insisted that he was responsible for his team’s negligence, which ultimately saw him punished.
