MIAMI — Charles Conwell of the Four State Franchise has had a change in venue and date for his next outing.

Originally scheduled to fight March 9 in Deadwood, North Dakota, as part of a nationally televised card on Showtime, for former Olympian now will be in action Saturday, March 5 at the Hollywood Casino in Columbus, Ohio.

Conwell announced the change in a post Wednesday via Twitter: “Sorry My Fight Date Has Been Moved From March 3rd To March 10th.”

“Had a chance to fight in Ohio,” promoter Tony Holden said in a text.

Conwell grew up and continues to train in Cleveland, Ohio.

This will be his first action since Nov. 17 in Cleveland when he picked up a six-round unanimous decision over Roque Zapata.

Conwell carries a 6-0 record (five knockouts) into Saturday’s fight.

An opponent still hasn’t been announced.

“He (the opponent) just fell through,” Holden said.

Three of Conwell’s first five fights were in Miami.

The two main events at Columbus will be title fights.

Jamie Walker (8-0-1, 3 KOs) of Columbus faces Skender Halill (15-2, 3 KOs) of the Bronx for the vacant WBA-NABA USA super welterweight title.

Brian Holstein (13-7-1, 7 KOs), of Dublin, Ohio, and Nick Kisner (19-4-1, 6 KOs) of Baltimore will be battling for the WBA-NABA USA cruiserweight title.

Holden said heavyweight Trey Lippe-Morrison and super lightweight contender Ivan “The Beast” Baranchyk still will be part of the Shobox card in North Dakota.
