London Irish could be suspended from the Gallagher Premiership as speculation continues to rage about their future amid a possible takeover by an American consortium.

The Rugby Football Union says that, along with Premiership Rugby and the Rugby Players’ Association, it is “seeking to take action to obtain greater clarity on the future of London Irish”.

The RFU said: “The proposed takeover of London Irish by an American consortium has led to a significant amount of uncertainty and speculation about the future of the club, which is having an impact on players, staff and fans of the club.

“It is imperative that the club will be in a position to take its place in the Gallagher Premiership in season 2023-24 and to complete that season.”

A deadline of May 30 has now been set by the RFU in what is an increasingly grim saga, with Irish having reported debts of £30milliom.

By that time, a takeover of the club must have been completed and approved by the RFU, with the buyers undertaking to provide all required working capital to meet the club’s obligations for at least next season, or the club showing that it will continue to be funded to operate throughout next season.

The RFU added: “If the club fails to meet these conditions, it will be suspended from participating in the Premiership (and other competitions) in season 2023-24 to avoid a scenario where the club enters insolvency mid-season, with the corresponding and substantial impact that has on players, staff and fans, as well as on the remainder of the league.

“This deadline was set to give enough time for the buyers to provide the information needed and for the transaction to complete.”

Wasps and Worcester entered administration earlier this season, resulting in their expulsion from the Premiership.

It meant the Premiership dropping to 11 clubs, with the most fraught campaign in English domestic rugby history reaching its conclusion on May 27 when Saracens and Sale Sharks contest the final at Twickenham.

Irish, meanwhile, narrowly missed out on a place in the title play-offs, finishing fifth, three points behind Northampton.

Alex Sanderson has described Sunday’s play-off clash against Leicester as “a game of grand magnitude” as Sale Sharks target a first Gallagher Premiership final appearance since 2006.

Sale beat Leicester 45-20 at Twickenham 17 years ago, helped on their way by 23 points from fly-half Charlie Hodgson, while captain Jason Robinson became the first player to win Grand Finals in both rugby codes.

The Sharks have featured in just one play-off occasion since that season, though, shipping 40 points against Exeter in 2021.

Standing in Sale’s way at a sold-out AJ Bell Stadium this weekend and a return to English rugby headquarters are the reigning Premiership champions.

When the clubs last met in Greater Manchester Sale ran out 40-5 winners, while Sharks finished second behind Saracens across the regular domestic season.

“Thankfully, this isn’t our first rodeo of recent times with this group,” Sale rugby director Sanderson said.

“We have learnt from two years ago how to manage these kind of moments better.

“It is a game of grand magnitude which we are looking to enjoy and embrace, not to be overwhelmed by. That is the challenge.

“Our excitement exists within this bubble. You don’t want to talk about the further reach because it can become overwhelming, as it did two years ago.

“You have to stick to process while being aware of the buzz around. It has been really, really busy around the ground and there is lots going on this weekend.

“We feel the support more than we ever have done. We have just got to come back to what has been working well for us, which is communicating well and training hard.”

It is difficult to under-estimate the drive that Sale have taken from their play-off loss against Exeter two years ago.

Had they beaten the Chiefs – also in Devon – during the final round of regular-season action a week earlier, then it could have secured a home semi-final.

Sanderson added: “We have been working towards it and building for this for two years, certainly since a year last Christmas when we realised we had a lot of work to do as an organisation.

“Since then, we have looked at how we can give ourselves these kind of opportunities.

“Now we are here, it feels like we have earned it. It’s less of a fairy-tale and there is less emotion around this occurrence than there was two years ago.

“We have referred back to the players, in particular seven or eight of them who have won the big trophies in the past, and how they have managed these weeks, how we can manage these moments better.

“It is a general understanding of how we deal with it, make sure it doesn’t change us, but be aware that it is there.”
