Chris Eubank Jr could fight the winner of Andrade-Williams, says promoter
"I'd love to promote that fight because the build-up would be naughty!"
Welshman Williams, also known as 'The Machine', is hoping to cause an upset and win his first major world title.
Eubank Jr (29-2, 22 KOs) returns to the ring on May 1 against fellow Briton Marcus Morrison, on the undercard of Dereck Chisora and Joseph Parker's heavyweight clash.
When asked about Eubank Jr facing the winner of Andrade vs Williams, Sauerland told Sky Sports: "Andrade-Williams is a great fight. If Williams wins that, he's a character.
He came back with a dominant win over JJ McDonagh in Saudi Arabia later that year before beating 2008 Olympic champion James DeGale in a scrappy affair.
If he manages to get past Morrison next month, Eubank Jr could target a major bout against Saul 'Canelo' Alvarez or Gennady Golovkin later this year.
