The German has not competed since suffering an ankle injury during the Roland Garros semi-finals against Rafael Nadal. Zverev underwent surgery shortly thereafter.

“After further examination in Germany, we received confirmation that all three of the lateral ligaments in my right ankle were torn,” Zverev wrote on Instagram at the time. “To return to competition as quickly as possible, to ensure all the ligaments heal properly, and to reclaim full stability in my ankle, surgery was the best choice. My rehab starts now and I’ll do everything to come back stronger than ever!”

Zverev reached his lone Grand Slam final at the US Open two years ago and owns an 18-7 record at the hard-court major. He is currently the No. 2 player in the Pepperstone ATP Rankings.

The US Open qualifying event will begin on Tuesday, with the main draw being held from 29 August through 11 September.
