Novak Djokovic shrugs off wrist injury at United Cup

Novak Djokovic received treatment for a wrist issue during his 6-1 6-7(3) 6-1 win over Jiri Lehecka at the United Cup on Tuesday as Serbia squeezed past the Czech Republic 2-1 to reach the quarterfinals.

Djokovic drew Serbia level at 1-1 in the $10 million mixed team tournament and had been scheduled to compete in the mixed doubles decider with Olga Danilovic before being replaced by the 20-year-old Hamad Medjedovic.

The young Serbian duo overcame Petr Nouza and Miriam Kolodziejova 4-6 7-6(2) 10-8 to send Serbia into the last eight where they will play hosts Australia on Wednesday.

Djokovic, gearing up for a tilt at a record-extending 11th Australian Open title this month, appeared to be bothered by his right wrist in practice and occasionally grimaced in the opening set at the RAC Arena in Perth.

The Serb had his wrist worked on by a trainer after the first set and Lehecka sensed an opportunity, winning the second set in a tiebreak.

Djokovic took a medical timeout before the start of the third and came out firing, running up a 5-0 lead before sealing the match.

"(The injury) happened in the warm-up today before the match. I basically got constant treatment before the match, during the match, after the match," the 36-year-old told reporters.

"It's not the first time that I have faced these kind of circumstances... these things happen. I think it's not a major concern, because I still managed to finish the match and managed to play well, even though I maybe wasn't feeling 100%.

"Hopefully I'll have enough time to recover for tomorrow's tie against Australia."

Wimbledon champion Marketa Vondrousova had earlier given the Czechs a 1-0 lead by beating Danilovic 6-1 3-6 6-3.

Poland will take on China in Wednesday's other quarter-final in Perth.

Meanwhile, Greece were stunned by Chile in their Group B opener, with Maria Sakkari and Stefanos Tsitsipas losing 6-7(5) 6-3 10-6 to Daniela Seguel and Tomas Barrios Vera in the mixed doubles decider at Sydney's Ken Rosewell Arena.

Sakkari beat Seguel 6-0 6-1 in the opener before Chile's Jarry downed Stefanos Sakellaridis 6-3 3-6 7-5 to level the tie after the Greeks decided not to field Australian Open runner-up Tsitsipas in the singles.
