The Club and McKinnon were in the midst of finalising a contract extension prior to the young forward’s injury in round three.
CEO Matt Gidley said the Knights would honour its contract offer, with McKinnon guaranteed employment at the club. The details of his employment will be discussed with McKinnon when he is ready.
“Alex is a wonderful talent on the field and a better Clubman off the field,” Gidley said.
“While we remain hopeful Alex will make a full recovery, we are pleased to extend his contract at the Newcastle Knights because there is no doubt he’ll be a valuable employee.”
