Tyson Fury's return to the ring remains in doubt after the British Boxing Board of Control (BBBofC) insisted the heavyweight's licence to fight is still suspended.
The 28-year-old tweeted on Monday that his return to boxing could be as soon as May, with an opponent still yet to be named.
The BBBofC maintain that Fury would need to provide medical records to prove he's fit to box - and that an anti-doping hearing still needs to take place.
"My understanding is a fact - he's suspended, so that's it," BBBofC general secretary Robert Smith told Sky Sports.
"He's got a number of issues to consider before we even consider lifting a suspension.
"We've not had any contact with Mr Fury or any of his team since he was suspended. We understand there is a hearing taking place for anti-doping, and until that matter is dealt with, the suspension will stay in place.
"[UK Anti-Doping] carry out all of our anti-doping issues. His BBBofC [license] is suspended until his UKAD hearing, on our behalf, has taken place. I'm hoping to hear a final date shortly, within the next month or so."
Fury today tweeted: "I will be boxing on a BUI boxing Licance [sic] from now on, want nothing more to do with BBOC, all they do is fine me anyways, boom."

Fury has been out of action since last October, after admitting he used cocaine to treat his depression. As part of his road to recovery, Fury was required to take some time away and relinquish his WBO and WBA world heavyweight title belts.
"I'm going through a lot of personal demons, trying to shake them off," he told Rolling Stone magazine last October. "This has got nothing to do with my fighting – what I'm going through right now is my personal life.
"They say I've got a version of bipolar. I'm a manic depressive. I just hope someone kills me before I kill myself."
Fury has not fought since winning the lineal heavyweight world titles in 2015. He was scheduled to face Wladimir Klitschko twice - pulling out first because of an ankle injury and then due to mental illness.
Of his continued substance abuse after abandoning his training camp last May he told Rolling Stone: "From that day forward, I've never done any training. I've been out, I've been drinking. I'm on the verge of becoming an alcoholic.
"I'm drinking Monday to Friday to Sunday. I can't, I can't deal with it, and the only thing that helps me is when I get drunk out of me mind and that's it. I don't tell lies, I've no need to tell lies. I've taken drugs, cocaine, on many many occasions for the last six months. Not to enhance my performance – cause I've not been performing.
"I've been out drinking, drugging, acting like a lunatic, being a fool. All to try and feel better in myself. But nothing can suffice my thirst no more, I'm finished. All the drugs and drink in the world ain't gonna make me happy no more. Nothing makes me happy anymore because I have gone past the point of happiness. There is no returning for me anymore. I am finished."
