Errol Spence Jr will make the first defence of his IBF welterweight title against former world champion Lamont Peterson in New York in January.
The American ripped the IBF belt from Kell Brook with an impressive stoppage victory in May and had hoped to head directly into a unification bout.
"My goal is to unify the welterweight division in 2018, but this fight is a true test and Lamont Peterson is a veteran that I definitely will not overlook," said Spence Jr.
"I sparred him in the amateurs and I know what he brings to the table. I have to get through him to achieve my goals and that is what I plan on doing January 20th."
