Brisbane Heat coach Darren Lehmann will defend his right to speak his mind on Thursday when he faces the music over his controversial outburst against West Indian allrounder Marlon Samuels’ bowling in the Big Bash League.

Lehmann’s Cricket Australia (CA) code of behaviour hearing will be held via a phone hook-up before the Heat travel to Sydney to play the Thunder in a must-win match for both struggling sides.

The former Test batsman is in hot water after questioning Samuels’ fast-paced off-spinners in Brisbane’s five-wicket loss to the Melbourne Renegades last weekend.

Samuels was banned from the Indian Premier League earlier this season for a suspect action but has been cleared to play in the BBL.

The 31-year-old Jamaican has reportedly been mentioned by one umpire in the BBL, where three mentions would result in him being sent in for testing under CA’s doubtful bowling procedure.

Lehmann on Wednesday said he would continue to hold true to his opinions.

He’s been alleged to have breached breached Rule 9: Detrimental Public Comment in CA’s code of behaviour.

The rule states players or officials must not “denigrate or criticise another player or denigrate or criticise an official, umpire, referee or team.

Lehmann was angered by Samuels bowling his quicker ball up towards 120km/h with a suspect bent-arm.

“I just want something done. He couldn’t bowl in the IPL last year, yet he can bowl in the BBL,” said the Heat coach.

“If he’s deemed legal, I’m totally understanding of that. But from my point of view, from 20 years of cricket, I’ve got a problem with 120km/h off no (run-up) steps.”
