Two players have been withdrawn from Australian Open qualifying tournament in Doha and put into hotel quarantine after returning positive tests for COVID-19.

American Denis Kudla, seeded No. 4 in the qualifying event which is being held outside of Australia for the first time, was withdrawn following a 6-4, 6-3 first-round win over Elliot Benchetrit of Morocco on Monday. Francisco Cerundolo of Argentina beat Guillermo Garcia-Lopez of Spain 6-2, 6-4 before he was withdrawn.

Tennis Australia confirmed in a statement there had been two positive tests at the tournament and both men had been transferred to a government-run medi-hotel, where strict quarantine procedures were in place.

"Local health authorities, the tournament physician and medical team are monitoring each individual. Contact tracing is currently underway to notify close contacts," the statement said.

The withdrawals mean Australian wildcard entry Dane Sweeny and Mario Vilella Martinez of Spain get walkovers into the third round of qualifying.

Australian media reported that match officials were made aware of Kudla's positive test while the American was leading 5-3 in the second set, but planned to wait until the regulation change of ends following the subsequent game to notify both players.

Kudla broke serve to win the match, meaning both he and Benchetrit were out of the tournament. If there hadn't been a break of serve at that time, the match would have been stopped after the ninth game of the second set and No. 221-ranked Benchetrit would have advanced to the next round.

Australian Open organisers said all players who started in the qualifying tournament had returned at least one negative test after arriving into Doha, where they were tested on arrival and isolated until they returned a negative result.

The players and their teams are also being tested every four days during the event and, if there's a positive case, Qatari health authorities must inform the tournament in writing.

The Australian Open has already been delayed by three weeks and is now scheduled to start February 8 because of travel restrictions and quarantine arrangements in place for the COVID-19 pandemic.

All players arriving in Australia will be tested on arrival and must isolate until they receive a negative test result. Then they'll be required to undergo a mandatory 14-day hotel quarantine which will involve daily testing for the coronavirus.
