Ashleigh Gardner has been cleared of concussion after the allrounder's bizarre collision with Georgia Wareham before Australia's Twenty20 against New Zealand.

Gardner missed Australia's series-opening win in Mackay on Thursday night, after she and Wareham clashed heads during a warm-up game.

Wareham has also been cleared of any concussion symptoms after recovering from the knock to play in the five-wicket win.

Gardner, the reigning Belinda Clark Medallist, initially laughed off the incident before leaving the ground in tears.

The 27-year-old has had a wretched history with concussions with seven throughout her professional career.

The issue prompted Gardner to see a neuropsychologist in 2018, after suffering four in the space of 20 months.

Saturday's news will therefore come as a welcome relief to Gardner, with both she and Wareham a chance to play the second T20 against New Zealand in Mackay on Sunday.

Australia also have other injury concerns ahead of next month's World Cup in the UAE with Grace Harris (calf) and Kim Garth (knee) both missing the New Zealand series.
