Last Saturday’s victory in three rounds saw Collins land the Commonwealth Featherweight Title at New Douglas Park in Hamilton on Saturday.
Promoter Dennis Hobson, who put on a successful joint fight card with Sam Kynoch, praised Collins’ performance afterwards.
Hobson told British Boxing News: “Nathaniel is still developing. He doesn’t need to rest on his laurels. He’s super talented and made a real statement against the Ghanaian.
"He went into another gear and Williams just couldn’t live with it.
"He’s definitely a star in the making; I don’t want to get too bullish about what he might win, but I think he has so much potential.
"He’s got a bit of a swagger in a nice way, and I think we can have some big nights with him in Scotland if he fulfils his potential.”
Broadcast live by Fightzone, Hobson and Kynoch staged an eight-fight card that packed in some fan-friendly action.
The evening also featured Collins’ fellow Scot Dean Sutherland also going home with a belt around his waist after beating Mexico’s Jose Antonio Delgado Velazquez via a TKO in seven to claim the World Boxing Organisation Youth Welterweight Title.
Billy Stuart was unable to make it three titles in a row for Scottish fighters though after being edged out against another Mexican, Alejandro Jair Gonzalez, for the International Boxing Federation Youth Super Bantam Title.
