Nick “King” Kyrgios will have to wait a little longer to make his UTS debut.

After missing the first ever UTS Los Angeles event because of injury last month, the Australian had been scheduled to play in Frankfurt, from September 15-17.

But the 28-year-old, who had knee surgery in January, has not still not recovered from the wrist injury which also forced him to pull out of this month’s US Open.

Kyrgios attended the LA stop of the UTS Tour and ended up acting as the coach for American Frances Tiafoe.

The former Wimbledon runner-up has played just one event this year, in Stuttgart just before Wimbledon. His replacement in Frankfurt will be named in the coming days.

Daniil “The Chessmaster” Medvedev heads the Frankfurt field, with the winner assured of a place in the UTS Grand Final in December.

Wu Yibing became the first man to book his place in the four-man Grand Final after winning in Los Angeles.
