Nick Kyrgios has evaded punishment after answering his phone on court before a mixed doubles match at the Australian Open on Saturday.

The Aussie bad boy came under scrutiny after taking a call from his mates before his match with new girlfriend Ajla Tomljanovic, prompting an overnight investigation by tennis officials.

Players are not allowed to use their phones during matches, however the 20-year-old took the call before the pre-match meeting.

“A referee reviewed the situation,” the statement said.

“As Nick walked on to the court before his match he answered a phone call then hung up. This happened prior to the pre-match meeting and no further action will be taken. The incident has been closed.”

The incident took place during his straight sets loss against No.1’s Ivan Dodig and Sania Mirza, with Kyrgios later revealing the call was from his friends.

Tour policy stipulates that a “A player is not allowed to use any electronic devices (eg CD players, mobile phones, etc.) during matches, unless approved by the supervisor”.

“Some of my friends called me,” Kyrgios said.

When questioned on whether the call was important, Kyrgios answered: “Kind of, not really”.
