Sydney - Australian Twenty 20 international Mitchell Marsh has been sent home from the Centre of Excellence in Brisbane for disciplinary reasons, Cricket Australia said on Saturday.
The 20-year-old West Australian all-rounder was ordered home to Perth after being declared unfit to train on Saturday following a night out, CA said in a statement.
"While the incident in isolation was not serious, he was already on a final warning," CA said.
"As such, it was decided he should be sent home to Perth."
Marsh re-signed with Western Australia this week despite reports he was looking to move interstate because he was unhappy with WA's initial contract offer.
The powerful middle-order batsman and medium-pacer has represented Australia in three Twenty20 internationals and one one-dayer.
He is the youngest son of former Australian Test and one-day international opening batsman, Australia and Sri Lanka coach and Australia team selector Geoff Marsh.
