Further criticism followed over Luke's decision to honour a perpetrator of domestic violence before he admitted he had made an error in judgement.
"I understand yeah fair enough I won't write the name on my wrist that was a stupid move. Especially given the circumstances," Luke wrote.
The thread continued to gain traction and Luke clarified his stance further, with another message reading: "...I don't support his actions. To be fair I want to kick his arse for laying his hands on a female. I'm just there for him...I'm simply saying that me and my family are there to support somi if he needs it. If I could re write the message with it again I would change so that I can detail so that people don't think I am sending the wrong message..."
Earlier today, Kiwis coach Stephen Kearney spoke glowingly about Luke's contribution to their preparations for tomorrow's tournament decider, after a shoulder injury to Thomas Leuluai saw the Rabbitohs rake recalled to New Zealand's starting side.
"He's been fantastic," said Kearney. "He along with the rest of the group were disappointed for Tommy, that he's sustained an injury that's going to keep him out for a while."
Kearney agreed with suggestions Luke could treat the Four Nations final like his own personal grand final, after suspension ruled him out of both the Rabbitoh's premiership success last month and the Kiwis opening Four Nations win over Australia three weeks ago.
"I haven't spoken to him about that but I guess in his mind he could use this as his grand final. If he wants to use that [as motivation] I'm sure he will but he's been great all week in terms of preparation and controlling the middle forwards. I'm expecting a big performance from him tomorrow night.
