In perhaps the first move that has not won universal acclaim within the game, ARLC chairman Peter V'landys confirmed this week that matches will be overseen by one on-field referee for the first time since 2008.

V'landys said the move came in response to fan polls calling for the return to one whistle-blower and will also see a significant reduction in costs.

A number of players and coaches have spoken out against the change - and the implementation of a six-again call in place of ruck penalties - but V'landys has won high-profile support from leading coaches Wayne Bennett and Ricky Stuart.

McGregor is more on the fence than his peers, but said mid-stream changes are never ideal.

"In 2008, when they made the change from one referee to two, it was in response to the demands of the game and because the pace was too quick for one referee to control the ruck and a good 10 metres," McGregor said.

"Now 12 years later we change it back to the one referee, is it the right timing with all eyes on the game... that's questionable right now.

"There's a lot of conversation around it but not a lot of clarity around it, we've just heard that it's coming in. We're less than two weeks away from playing now, so it's going to be crammed in, but the game's back on and that's the most important thing.

"No one's got any advantage right now because we've all been given the same rules to play under at the same time."

There'll inevitably be teething problems, but McGregor found some positives for his side, particularly in the six-again rule that will replace ruck penalties.

"We always look for a negative around things so we've got to start to look for positives around it," McGregor said.

"The game will flow cleaner with the six-to-go, that's a really good rule to try. The other rule change with the six-to-go probably complements the one referee where he can just call it on the run and keep the game flowing which will help us as a footy team.

"We give away the least amount of penalties in holding people down. We've got two really experienced Nines in Bully [Issac Luke] and Cam [McInnes] that can take advantage of the six-to-go and a mobile footy team that can defend it.

"I'm not sure the timing's right, but it's in place and we've got to get on with it and make it work."

The Dragons will resume their season against the Warriors on May 30, with both sides looking to arrest an 0-2 slide.

McGregor and counterpart Stephen Kearney will need to rely on intuition more than form given they last played nine weeks ago and were only cleared to resume contact training this week.

"Those [first] two games are a long way in the rear vision mirror to be honest, we could've won either but we didn't," McGregor said.

"We've got 31 of 32 players available and ready to play. Obviously Cam will go back into [hooker] and you've got other players who'll definitely be in the starting side.

"Tariq [Sims] didn't play round two, Korbin [Sims] didn't play the first two games, Mika [Ravalawa] wasn't available for round two so they're back in the mix.

"Only 17 can make the side so everyone's out there doing their best to make that squad for round three so we're giving everyone a really good chance over the next week and a half."

The Dragons will face the Bulldogs in round four, with the remainder of the revamped draw unlikely to be known for at least another week.
