Bradford Bulls' future appears in doubt after the club entered administration for a third time.
The Bulls - four-time Super League champions - were placed in administration in 2012 and 2014 - the latter resulting in the club being docked six points and led to their relegation from the Super League.
A statement released by chairman Marc Green on Monday revealed that the step had been taken following a dispute with Her Majesty's Revenue and Customs (HMRC).
"I have been talking to a number of serious investors and purely the pressure from HMRC has forced the club to be put into this position to save its future," he said.
"There is a dispute between ourselves and HMRC which we have been working hard to resolve since the winding up petition was issued and despite two adjournments from the courts to resolve this matter we have been unable to do so. We were concerned over the ability to secure a third adjournment and therefore this action became unavoidable to protect the club.
"I will be working closely with the administrators over the coming weeks and it is my intention to regain this club from them within the shortest practicable time frame.
"Regardless of whether I remain at the helm of this great club, I will ensure all memberships already purchased for next season will remain valid, as will the offer under which they were purchased. I believe the future of Bradford Bulls is still strong."
