Novak Djokovic’s right elbow was treated by a trainer in the third set of an otherwise matter-of-fact 6-2, 6-1, 6-4 victory over Kyle Edmund

Sunday night that put the defending champion in the US Open quarterfinals for the 10th consecutive year.

Djokovic was finally forced to play another full match after competing for a total of 31 minutes over the preceding five days because of injuries to his opponents in the second and third rounds.

And while Djokovic looked quite good for the first two sets and at the very end, there was that interlude that included the medical visit.

Ahead 2-0 in the last set, Djokovic got broken, starting a stretch of three games in a row for the 84th-ranked Edmund. Djokovic had his elbow massaged at a changeover; a trainer worked on his right arm in the first round.
