Uisma Lima knows he's far from a household name. But he's hoping that’ll change on October 11.

Lima (14-1, 10 KOs) believes he’ll be celebrating a huge win over Jaron Ennis at Wells Fargo Center in Philadelphia, a former Ring, IBF, and WBA welterweight championl officially making his 154-pound debut.

By all accounts, Lima has no problem admitting that the Ennis was the best at 147 pounds. However, now that he’s moved up, Lima intends to play spoiler.

“I’m going to take on the world number one welterweight,” Lima wrote on his Instagram page. “He is going to put on weight. I’ll level up and prove that you aren’t walking in my division.”

At 32, Lima has spent most of his career in the shadows. Although he has beaten three consecutive undefeated fighters, he’s yet to face someone elite.

Ennis, though, is considered one of the best fighters in the world. His goal was to become an undisputed champion, but after beating Eimantas Stanionis on April 12 in Atlantic City, New Jersey, he decided to leave 147 behind.

Ennis (34-0, 30 KOs) doesn’t see this fight going the 12-round distance against the Portuguese native.

“It’s the biggest challenge of my career,” Lima wrote. “I’ve prepared my entire life for this moment.”
