The bout will be shown live on Sky Sports. Fisher, known as the Romford Bull, enters the contest after completing his first full training camp with coach Tony Sims. His opponent, Belgian heavyweight Pirotton, has said he is not intimidated by the prospect of a revamped Fisher and intends to rely on composure and tactics.

Pirotton pointed to Fisher’s new training links with Sims and assistant trainer John Ryder, but said he would look to use his boxing judgement, movement and work rate. He also believes the pressure of fighting in front of Fisher’s home support could become a factor if the contest does not unfold as the crowd expects.

Fisher has praised Sims for building confidence, fitness and tactical preparation in his fighters. He expects Pirotton to be durable, ambitious and active to the body, while saying his team has identified areas it hopes to exploit. Fisher has also acknowledged that his willingness to take risks can leave him vulnerable.

The fighters arrive with contrasting plans: Fisher is aiming to build on his work under a new coaching team, while Pirotton is seeking an upset by staying focused and disrupting the home favourite’s rhythm. Their weigh-in figures put them within 2.4 pounds of each other, but the result will depend on what happens once the bell rings at the Copper Box.
