Shane Warne has been reported for his second code of behaviour breach in as many games, after his Melbourne Stars were beaten by Perth Scorchers in a last-ball thriller in their Twenty20 Big Bash semi-final.

Warne’s been reported by Cricket Australia after opting not to name himself as captain on the official team sheet in what could have been his final competitive match.

The 43-year-old, making his return at the WACA Ground on Wednesday night from a one-game suspension following a foul-mouthed altercation with Marlon Samuels during the Melbourne derby, now faces a second suspension.

“Cricket Australia (CA) has today advised that Shane Warne has been reported for breaching CA’s Code of Behaviour in tonight’s KFC T20 Big Bash League Big Semi Final between the Melbourne Stars and Perth Scorchers,” Cricket Australia said in a statement.

“Warne is alleged to have breached Rule 5: Laws of Cricket and Spirit of the Game. On 5 December 2012, KFC T20 Big Bash League teams were sent a Memo by Cricket Australia. Under the heading ‘Over Rates’, the Memo stated that ‘If a team’s official captain is selected but not named as captain, this will be considered against the Spirit of Cricket and may attract a Code of Behaviour charge’.

“For tonight’s match, James Faulkner was listed on the Melbourne Stars team sheet as captain and took part in the coin toss with Perth Scorchers captain Simon Katich. Warne had previously been issued with one strike for a slow over rate violation, with a second strike this season resulting in an automatic one-match suspension.

“The time and date of the hearing is yet to be determined.”

Warne did not bat or bowl as his Stars suffered an eight-wicket defeat on the Duckworth-Lewis method.

They had appeared set for victory only for James Faulkner’s last ball to be called a no-ball.

Mike Hussey hit the subsequent free hit for four to send the Scorchers into their second consecutive home final, against the Brisbane Heat on Saturday.
