Tyson Fury has been cleared to fight again after he accepted a two-year backdated suspension from the UK Anti-Doping (UKAD).
Fury, 29, beat Ukrainian Wladimir Klitschko in November 2015 in a huge upset in Germany - but has not fought since.
Smith predicted Fury will need "one or two warm-up contests" before challenging for the world title again.
"Of course a rematch would be a good thing, but for me right now the only that counts is Povetkin, and if I win the fight I'll fulfill my dream of a world title fight", says Hammer.
On December 15 he will take on Russia's Alexander Povetkin (33 fights, 32 wins, 1 defeat) in a final WBO, WBA world title eliminator - with the victor being in line for a crack at world champions Joseph Parker and Anthony Joshua.
"Fury tweeted: "@anthonyfjoshua where you at boy?

Highie Fury boxed very recently against Joseph Parker for the WBO world title action in Manchester so will have no issues anyway with his boxing license.
Tyson Fury blamed the result on eating uncastrated wild boar.
Another option is for Fury to take on another British boxer Tony Bellew, who played "Pretty Ricky" Conlan in the 2015 Rocky-spin-off movie Creed.
"So get it out of your mind that it is cemented that I am going to go with you guys because I have a vast array of board of controls around the world, with open arms welcoming the gypsy king and treat me like the king I am and not like some piece of s***".
The 29-year-old has also had to battle self-confessed problems with cocaine use and depression as well as a negative drugs test returned in 2015.
As part of the compromise deal, UKAD withdrew a charge against Tyson Fury of failure to provide a sample in September 2016. A BBBofC statement said: "The British Boxing Board of Control acknowledges United Kingdom Anti-Doping's decision in relation to Tyson and Hughie Fury".
With an April comeback in mind, Fury still has some way to go in order to have everything in place for his return on the back of accepting a two-year backdated suspension from UKAD over a positive test for Nandrolone.
