Middleweight Tony Harrison called out former titleholder Errol Spence Jnr after his win on Saturday night in Detroit.

Harrison earned a fourth-round knockout over Brian Chaves in the co-feature of a Salita Promotions card at the Fox Theatre. The time of the stoppage was 2 minutes and 59 seconds.

After the fight, Harrison called out Spence, a former unified welterweight champ.

“I think a fight with Errol Spence will please everybody,” Harrison, who won a junior middleweight title back in 2018, said after the fight. “Let’s give the fans what they want to see.”

Harrison, 35, made the final seconds of the fight matter, but he started laying the foundation as early as the first round. After he took some clean shots from Chaves – some of which seemed to rattle him – Harrison dropped his opponent with a left hook followed by a right hand as the round concluded.

The third round was a near replay of the first. Chaves, a 33-year-old from Buenos Aires, Argentina, landed some clean shots on Harrison, only to be dropped in the final second by a right hand. Harrison finished the fight by landing a left hook to Chaves’ body a round later.

Detroit’s Harrison is now 31-4-1 (22 KOs). Chaves, 15-8 (6 KOs), has now been stopped in seven of his past eight fights.

Spence, 28-1 (22 KOs), hasn’t fought since his lone career loss to Terence Crawford in July 2023. It’s unclear whether Spence, a 35-year-old from Desoto, Texas, would be interested in a matchup with Harrison – or any other fight, for that matter.

Heavyweight Pryce Taylor, of Brooklyn, New York, won an eight-round unanimous decision over Michael Coffie of Orlando, Florida.

Scores were 79-73, 80-72 and 80-72 in favor of Taylor.

Taylor, 29, controlled the majority of the action, outworking his opponent as he improved to 10-0 (6 KOs).

The 39-year-old Coffie fell to 13-6 (10 KOs).

In the opening bout, heavyweight Sardius Simmons, of Flint, Michigan, knocked out Colby Madison, of Baltimore, at 1 minute of the first round.

Simmons, 32, dropped Madison with a clubbing left hook, from which Madison was unable to recover and get to his feet.

Simmons improved to 5-0 (3 KOs), while the 42-year-old Madison now holds a record of 11-11-3 (7 KOs).
