The Welsh government has come under pressure to finalise the date for Chris Eubank Jr vs Liam Williams by the British Boxing Board of Control.
It is hoped the all-British grudge match will go ahead on Saturday February 5 in Cardiff, live on Sky Sports, but the date remains unconfirmed due to Covid restrictions imposed by the Welsh government.
Eubank Jr and Williams were previously set to fight a week earlier, on Saturday January 29, but the British Boxing Board of Control suspended all boxing throughout the month to allow doctors and medical experts to prioritise their work with NHS during the pandemic.
The BBBofC has now written to the Welsh parliament: "It is hoped that the Motorpoint Arena, Cardiff, will host a boxing tournament on Saturday February 5, 2022.
"This is a major event for boxing in Wales and needs supporters in attendance to make it viable.
"The British Boxing Board of Control fully understand the difficulties the Welsh government have in relation to the current situation in regard to the pandemic, however, the uncertainty in relation to an event taking place on February 5, 2022, is making the situation difficult in organising a major sporting event in Wales.
"As you are aware, the history of boxing in Wales is steeped with great Welsh boxers and due to the present circumstances over the last two years has resulted in major boxing events not being able to take place.
"Although we fully understand the Welsh government's position, it is hopeful that you may be able to clarify whether a boxing event can take place at the Motorpoint Arena with a full crowd on February 5, 2022. If this is not the position, the promoter Mr. Ben Shalom will have to look for another venue in England."
Cardiff is Williams' home city and he plans to welcome Eubank Jr with a hostile atmosphere for their middleweight clash.
"Respect is definitely not a word I would use for my feelings towards Liam," Eubank Jr previously said.
"This is a grudge match, a genuine domestic rivalry. It is personal. He has made it personal."
Williams has hit back: "We're not each other's type of person.
"I don't have much respect for him personally. I don't like the way he goes about his business.
"He's not my type of guy. He's not somebody I'd want to be friends with.
"I've said a couple of things to him online. Things I stand by."
