A second journalist within a week will have to undergo a coronavirus test after breaching social distancing rules by failing to observe a two-meter gap from players in Australia's National Rugby League (NRL), local media reported on Saturday.

Fox Sports' Hannah Hollis interviewed North Queensland Cowboys' Valentine Holmes on the sidelines after he suffered an ankle injury during a game against the New Zealand Warriors.

Hollis leaned across a fence surrounding the playing area as she interviewed Holmes and the Sydney Morning Herald reported the league had asked her to undergo a COVID-19 test.

Stringent health rules have been put in place to minimize the risk of players contracting the novel coronavirus during the competition, which was the first to resume in Australia following the shutdown.

Earlier this week, Michelle Bishop, a reporter for Seven News in Sydney, also underwent a test after Wests Tigers playmaker Benji Marshall greeted her with a peck on the cheek at training on Wednesday.

Bishop tested negative and Marshall was allowed to return to his team after initially being sent home.

NRL players have been isolated in 'bubbles' and are routinely tested.
