The former Newcastle forward is readying legal action against the game's governing body over the 2014 tackle which left him wheelchair-bound.

The lawsuit is also reported to include Jordan McLean, who was banned for seven games for his involvement in a three-man spear tackle that left McKinnon with a spinal injury. The Rugby League Players Association said McKinnon's injury had been life-altering and people should consider his position before judging him.

"Alex has the right to pursue any and all legal options available to him in relation to his injury, and it is appropriate that he has engaged his own legal representatives to assist him," the RLPA said in a statement.

"We also recognise there has been an emotional toll on those who played and officiated in the game between the Knights and Melbourne and particularly on those involved in the incident that resulted in the injury to Alex. 

“From the RLPA's perspective, we will seek to ensure that the rights of all parties are protected."

McKinnon expressed a desire to sue last year despite receiving the maximum $500,000 compensation payout from the NRL and about $1.2 million through fundraising efforts. McKinnon, whose legal team have reportedly met with NRL boss Todd Greenberg, has said that will be nowhere near enough in the long-term.

The Storm declined to comment.
