Billy Joe Saunders would consider a move to super-middleweight if he fails to nail a showdown with Saul Alvarez or Gennady Golovkin.
Saunders, 28, makes the second defence of his WBO middleweight title against Willie Monroe Jr in London on Saturday night and is Sky Bet's 4/11 favourite to win the fight, with Monroe Jr 9/4 and the draw 28/1.
An impressive win could land him a shot at the winner of Canelo v GGG who meet in Las Vegas a few hours after his showdown with American Monroe Jr.
Hatfield’s Saunders has seen potential showdowns against the middleweight divisions two biggest stars fall through over the last 12 months.
Saunders, who hasn’t boxed since last December, said: "I signed to fight both Golovkin and Canelo, but none of them have come off. If it’s going to happen, it’s going to happen.
"The inactivity has been stressful, but you crack on and deal with it. My last opponent, Avtandil Khurtsidze got arrested and the fight was cancelled. You just have to deal with it."
PRICE BOOST: Saunders to win by KO/TKO is 4/1 from 3/1 with Sky Bet!
If Saunders did make the move to 168lb he would be relying on his outstanding skills against naturally bigger men.
He added: "I am a big middleweight and don’t want to give my advantage away, but there is not a super-middleweight that I fear.
"Most of the top super-middleweights I have sparred and they will tell you I did well. Callum Smith is the only top British one I haven’t worked with.
"I will go to that weight, but when I have done my work at middleweight.”
