Callum Smith to make September 25th light heavyweight debut against Lenin Castillo

Keith Idec reports that former super middleweight champion Callum Smith is set to make his light heavyweight debut against former title challenger Lenin Castillo on the September 25th Anthony Joshua vs. Oleksandr Usyk card in Tottenham.

The fight will be “Mundo’s” (27-1, 19 KO) first since losing his belt to Canelo Alvarez last December and his first under the tutelage of Buddy McGirt. He’d seemingly struggled with the 168-pound limit for a long time, so it will be interesting to see what he’s capable of when he’s not wringing himself dry.

32-year-old Castillo (21-3-1, 16 KO), a 2008 Olympian from the Dominican Republic, has thus far fallen well short in his biggest fights. He’s most notably dropped wide decisions to Marcus Browne and Dmitry Bivol, and his only appearance since that latter defeat saw him stop unheralded Colombian Ronald Gonzalez in July. While he shouldn’t put up much of a fight against Smith, he can at least serve as a metric.

Matchroom has yet to reveal the rest of the undercard for that evening, but more info should arrive soon considering we’re just over a month out.
