Before Okolie defends the WBO cruiserweight title in the main event in Manchester, Clarke will go up against late replacement Bogdan Dinu in a heavyweight bout.
Team GB star Clarke is 5-0 as a pro, with four knockouts to his name. Last time out, in January, he stopped Kevin Nicolas Espindola, and Rydell Booker was supposed to be next for the 31-year-old.
Instead, “Big Fraze” will face Romanian Dinu (20-4, 16 KOs), who comes in on short notice.
Here’s all you need to know.
When is it?
Okolie vs Light will take place on Saturday 25 March at the AO Arena in Manchester.
The main card will start at 7pm GMT, with main-event ring walks expected to take place at approximately 10pm GMT.
How can I watch it?
In the UK, the event will air live on Sky Sports, which will also stream the fights live on its Sky Go app.
No US broadcaster has yet been announced.
Okolie – 1/10
