Lightweight Jalen Walker aims to show that one loss will not define his career. 

In April 2024, Walker lost to the 12-4 Alejandro Guerrero via seventh-round technical knockout. Since that fight, Walker has won three straight and is set to return Saturday against Joaquin Elian Silva Faccio at The Chelsea at the Cosmopolitan in Las Vegas. The bout will be on the undercard of Brandon Adams-Caoimhin Agyarko.

Walker, 15-1-1 (11 KOs), faces skepticism after being stopped as a prospect. Each performance from this point on will either confirm or dispel preconceived notions of where his career is going.

“I am on a comeback tour,” Walker said. “There are always battles, especially when you are favored to win, and the blue-chip prospect. I just internalized that better days are going to come.”

Walker, a 24-year-old from Los Angeles, recently changed trainers. He began working with Trevor Sambrano, who also trains Adams and has known Walker for some time. Sambrano was an assistant coach for some of his earlier fights. 

Walker believes that his loss was due to factors outside of his boxing ability. 

“I had strep throat,” Walker said. “I was on antibiotics leading up to the weigh-in.”

Last April, Walker recorded an eight-round unanimous decision win over the 14-5-1 Jerry Perez. The bout proved significant as Perez is known as a puncher. Just this February, Perez lived up to that reputation by knocking out prospect Tayden Beltran. 

“I didn’t know he could hit like that,” Walker said. “I wasn’t aware of his power.”

While Walker sets his sights on proving he is more than just one bad night in the ring, he learned something about himself in his last performance.

“Jerry Perez is a tough veteran who has been in there with some names,” Walker said. “I already believed in myself, but it was the evidence I needed.”
