The hardest whistle in rugby? Why officiating The 745 Game is unlike anything else

Professional referees are used to pressure, noise, and intense, split-second scrutiny. The 745 Game presents a different test altogether: two rugby codes, a hybrid lawbook, and two officials making one match work without refereeing the spectacle out of it.

For elite rugby union referee Luke Pearce and former rugby league official Ben Thaler, the hardest part is not pressure from the crowd. It is suppressing years of code-specific instinct while judging a game that keeps changing its point of reference.

The annual charity fixture takes its name from the shirt numbers of Rob Burrow (7), Ed Slater (4) and Doddie Weir (5). It brings rugby union and rugby league together to raise awareness and funds for Motor Neurone Disease (MND), using a format unlike anything either referee encounters in their usual competition.

Thirteen players line up on each side. Possession is limited to six tackles, yet scrums and lineouts remain. League-style play-the-balls sit alongside union tactics at the contact area. Two referees operate simultaneously: one concentrates on the tackle and ruck, while the other controls the defensive line, offside, and the wider flow of play.

The challenge is deciding which instincts to trust, which to ignore, and when a technically available whistle would damage the game more than it would help it.

In association with our partners at ACME Whistles, we caught up with league referee Ben Thaler and union ref Luke Pearce to see what makes refereeing The 745 Games so different, and special.

Asked to explain the format to somebody seeing it for the first time, Thaler's answer was immediate; "Complete chaos."

The chaos is deliberate. The format is designed to keep the ball moving, which immediately changes how strictly the referees can apply either code.

"A mixture. I like the idea that Ed and Rob Burrow had originally with Doddie, and that was to mix the rules of rugby union and rugby league together and try and get it where the ball was in play a lot more", adds Thaler.

That creates a problem deeper than memorising a new set of laws. Pearce and Thaler must continually recognise when their automatic reading of a situation belongs to the wrong code.

Union trains the eye towards entry angles, release, support, and contest at the breakdown. League demands an accurate tackle count, a legal play-the-ball, and disciplined defensive spacing. In The 745 Game, those pictures overlap. A referee can identify an offence correctly and still apply the wrong priority to it.

The solution is not simply to split the pitch in half. Both officials see the same collision from different positions, and their judgements must remain consistent enough that players know what will be tolerated.

That makes the partnership in the middle central to the contest. Instead of one referee leading and assistants supporting, Pearce and Thaler must share authority in real time.

Thaler explained: "One's behind the ruck, and one's keeping them back five metres.

“We want them to have the freedom to play. You could easily stand there and penalise everything and blow scrums every two minutes. But we want to keep the ball in play because that's what people come to see."

Each official therefore has to know when to lead, when to defer. The most technically complete performance could still be the wrong one if it fills a charity match with stoppages.

Pearce reduces that complex calculation to one principle: "It sounds daft, but it's a bit of common sense. That's all it needs."

For Pearce, one of England's leading rugby union referees, it isn't about remembering hybrid laws. It's remembering why everyone is really there.

"I think it's more grounding than anything else," he said. "We live in a world of professional sport and you chase your tail travelling around the world and we sometimes treat sport as the be all and end all."

The 745 Game provides a powerful reminder of what matters. He added; "There are bigger things in life than when you blow your whistle, you're right or wrong."

That perspective runs through every aspect of the event. Many of the players involved are former internationals. Some are household names from rugby union. Others are legends of league. Yet when they arrive at The 745 Game, status largely disappears.

"The only intention of every single person is to try and raise some cash for the people who are suffering terribly with this disease," said Pearce. "In fact, to do a game like this is the reason we all started in the first place.”

For officials who spend most weekends operating under intense scrutiny, that represents a refreshing change.

For Thaler, the emotional connection runs even deeper. His father passed away following Huntington's disease, a condition he describes as having many similarities to MND. The first 745 game came only weeks before that loss.

The invitation to referee came from the Burrow family. Thaler revealed; "My dad sadly passed away about a month after the first game."

"Lindsey Burrow had messaged me, and said, 'I just wanted to know if you would referee this game for Rob.'"

It carried extra significance because Thaler had known Burrow for most of his life. "I refereed Rob Burrow at 11 when he played at Featherstone Lions," he said.

What has struck both officials most is how effectively the event brings together rugby's two tribes. Historically, union and league spent decades operating in entirely separate worlds.

Thaler highlighted the irony. "Fifty or sixty years ago, me and Luke, the rugby union and rugby league referee, you kept apart."

Today, they share a changing room, and together they help oversee an event that unites two sporting cultures in pursuit of something bigger than rugby.

Pearce believes the spirit off the pitch is the most remarkable aspect. He recalled attending last year's event and seeing first hand people affected by MND.

"So many people nave put in so much work to make this happen – we just get to help oversee the chaos on the pitch!

"The coverage of players living with MND, and of those who have lost their lives to it, is harrowing. People I know, including Ed Slater, are suffering terribly, while Lewis Moody is at the start of that journey.

“It is daunting, but this charity matters because every pound raised supports families, builds awareness, and helps drive the search for progress.

"If this game can bring people together, put smiles on faces and make a meaningful difference, that is why we want to be involved."

Yes, the 745 format is a fascinating sporting experiment, but that was never the real objective.

As Pearce summed up; "If we can create something entertaining on Sunday and put a smile on people's faces and raise some much-needed money to support families living with MND, I guess that's the reason why we just want to be involved."

Thaler's conclusion was equally powerful. "If it means that 60 or 70 former players and a few old referees (and one youngish one) come together once a year to put an event on, to raise money and raise awareness, then I think it's great."

In an era when every rugby debate seems to centre on laws, officiating, and controversy, The 745 Game offers a timely reminder … sometimes the whistle matters a little less than the cause behind it.
