Fury has not fought competitively since he faced Wladimir Klitschko in Dusseldorf, where he won a unanimous points decision to claim the IBF, WBA and WBO world heavyweight titles.
However, he later vacated the belts, citing problems with depression and cocaine and has not fought since.
But now he appears to be planning to make a long-awaited comeback.
“Be ready to fight in April 2018 in a great fight!” Fury posted on Twitter.
“[And] again in the summer in a mega fight!
“[And] again in back end of year.
“3 big fights in 2018.”
Fury has several times promised to get back in the ring and said in an interview last month that he would be targeting unbeaten Brit and two-belt heavyweight champion Anthony Joshua.

“They call me the boomerang. I always come back. [Joshua vs Fury] is the fight people want to see and the fight I’d love,” Fury told BT Sport.
“I think it’s an easy fight for me with my boxing skill.”
He added: “I’ve got to get some weight off.
“I’ve lost nearly two stone in two weeks so everything is going really well for me at the moment.
“I’ve turned my life around. I’ve done a U-turn on everything and I’m feeling a lot better than I did before.”
