Kell Brook admits he is still in limbo after Devon Alexander pulled out of their title fight on February 23 with an arm injury.
The champion is likely to require up to six weeks off before preparing for a fight, providing the injury is genuine.
That was put into doubt when Floyd Mayweather tweeted that Alexander was favourite to fight him on May 4.
However, the consensus is that Mayweather's comment was a red herring and that Alexander will be forced to fight Brook by the IBF as his mandatory challenger.
For the time being, a devastated Brook is trying to stay focused on training.
"We heard they wanted to put me on the Danny Garcia bill (April 27) but now we're told that can't happen, so we're still in limbo," he told iFilm London.
"I've got to be professional about this, keep training and wait for more information.
"I don't know what's going to be happening so I'll just keep professional and keep doing my job.
"I want Devon Alexander. People don't know about me in America but after I do a job on Alexander they'd all know about me.
"He's been on my mind since before Christmas, I've been thinking about that man for 12 weeks and I want to rip that title off him.
"He's a genuine champion, he's a good fighter and I want to take it from him. I'm devastated about what has happened but my time has come."Tags: Devon Alexander , Kell Brook , Alexander-Brook , Alexander vs Brook
