Jack Catterall knows that boxing will come to an end. And possibly soon.

In the real world and boxing years, 32 wouldn’t be considered old. But the former 140-pound title challenger sees the finish line getting closer.

With possibly just a handful of fights remaining, the U.K. native made some changes.

For starters, he officially moved up to welterweight where he’ll take on Ekow Essuman on November 15 at Tottenham Hotspur Stadium. Catterall also has cut ties with trainers Jamie Moore and Nigel Travis and has teamed up with Philadelphia-based Derek “Bozy” Ennis.

Although it wasn't easy, he believes he made the right decision.

“I’m probably in the final chapters of my career and I wanted to give it everything I’ve got,” Catterall told iFL TV. “I believe this move is everything.”

Ennis' name has been hot for the last few years. His son, Jaron Ennis, is a former unified welterweight champ who he's trained from the beginning. He’s also guided Stephen Fulton to a world title at 126 pounds and helped develop Andy Cruz into one of the best 135-pounders around.

Catterall (31-2, 13 KOs) has been viewed as a good fighter. But even with several eye-catching wins, including over Regis Prograis and most recently, Harlem Eubank, Catterall wasn’t pleased with his performances. He racked up wins but still felt a need for change.

“It’s something I’ve not taken lightly,” Catterall said. “I’d be stewing on it. I assessed my performances of the last couple of fights and I think deep down, it was something my gut was telling me to do.”
