Michael Ennis will make his first appearance for NSW since 2011 as a late replacement for injured hooker Robbie Farah.
Ennis, 31, last played for the Blues in Queensland's 2-1 series win four years ago, but skipper Paul Gallen is expecting big things from his Sharks teammate.
"He's just a competitor. He's got more talk than niggle and he'll be great," Gallen said.
"He's been great from day one [of camp]. He hasn't been shy, he's really stepped up and been somewhat of a leader around the side as well, as he is in all sides and he'll be fine."
