Kearney, however, has joined fellow coaches Des Hasler of Manly and Roosters' Trent Robinson, in opposing the idea of dropping one referee.
"It's just too hard to implement that now. We've been used to two referees for a long time," Kearney told Newstalk ZB's Martin Devlin from the team's base in Tamworth.
"I know there's been a lot of debate about having two referees on the field but to throw that on us in three weeks time, I think that's too big of an adjustment," he added.
Kearney said the Warriors, who arrived in the New South Wales town last Sunday, will hopefully get to begin full contact training tomorrow after being restricted to training in groups of 10.
"It is supposed to kick off tomorrow - the full contact work. We're waiting for confirmation of that.
"It's worked out well that we've been able to focus on some fundamental skill early on in the week, obviously we'll start picking that up once we get together as a full team."
