On Friday morning, McLachlan admitted the AFL had erred in its handling of Reece Conca's "appalling" hit on Devon Smith last weekend, and should have referred the incident directly to the Tribunal.

 

Richmond's Conca received a two-match ban for his elbow to the back of the head of the GWS midfielder.

 

Hardwick said McLachlan's comments were unnecessary.

 

"I was a little bit disappointed with that," Hardwick said after the Tigers' 18-point win over Essendon at the MCG.

 

"Reece knows and he’s disappointed with his actions as are we. I don’t think we need to have the CEO come out and speak about it. It's done and dusted, let's leave it in the past.

 

"The Match Review Panel dealt with it so let's move on. I'll be sending him a please explain.”

 

Hardwick said Conca was "embarrassed" and would take to heart the comments made McLachlan.

 

Boxer and one-punch campaigner Danny Green lashed the League for its handling of the incident, saying it sent a poor message to the community.

 

"The AFL had a real chance to make a real stand against this kind of violence, which the whole of society is trying to abolish," Green told 3AW on Friday.

 

"The AFL should have taken a stand and said, 'You know what, son, we know you are sorry and you didn't mean it and wouldn't normally do it but we have to make a stand and stamp this type of behaviour out'."

 

McLachlan later said the incident should have been referred directly to the Tribunal, which would have allowed more scope for punishment.

 

"I thought it was an appalling act and I feel the Match Review Panel is constrained by it," McLachlan told 3AW on Friday.

 

"I think probably the right outcome here was to put this straight to the Tribunal because if you look at the rules, the application in this case was right of the MRP.

 

"But when you've got a guy, out of anger, running after a guy and hitting him from behind ... I just think it's a terrible, terrible act and I understand Danny Green's comments."

 

McLachlan said nothing could be done about it now, with no place for the AFL Commission to step in.

 

He said he had spoken to the MRP and AFL football operations boss Mark Evans, who is reviewing the citing process.

 

"I think we need to learn from it and understand what could have been done better if we feel that an outcome isn't right,” McLachlan said. 

 

Meanwhile, the League will begin monitoring the health of Essendon players. Testing led by chief medical officer Dr Peter Harcourt will start next week.

 

The players were involved in the Bombers' controversial supplements program in 2011-12.

 

"It's a proper process being worked through with the club led by Peter Harcourt, and it's an appropriate response," McLachlan said.
