The IBF welterweight world champion makes the first defence of the title he took from the 'Special One', when he takes on Peterson in the Barclays Center, New York, on January 29.
Spence Jr will not have boxed for almost eight months when he takes on a former sparring partner, but 'The Truth' is expecting a tougher test than he got at Bramall Lane, when a serious eye injury forced Brook to retire in the 11th round.
"You're going to see the same Errol Spence that you're used to," said Spence Jr.
