Ackerman was shoulder charged by Molo in a Queensland Cup match and died two days later in hospital.

Molo was twice more suspended for shoulder charges following his nine-week suspension for his tackle on Ackerman.

Coroner John Lock said the force of Molo’s shoulder charge on Ackerman was such that it caused death with the Broncos-contracted player making no effort to make a legitimate tackle.

Mr Lock said force was made to the chest and upper body of Ackerman rupturing an artery in his neck.

He said Brisbane failed to address his tackling technique and were more concerned with his welfare.  

Mr Lock said the Broncos, the code’s richest club, had the resources available to try and teach Molo how to tackle properly but failed to do so.

“Given the tragic outcome, and then the following incidents involving shoulder charges, there should have been some thought, given the issue ... to discuss it more with Francis at an appropriate time,” he told the Brisbane Coroners Court.

Mr Lock backed the decision not to lay criminal charges.

“He did not place himself in a position to wrap his arms,” Mr Lock said.

Ackerman left behind his wife and two children.

Molo is contracted to the Cowboys for 2018.
