Diego Lopes’ lightweight rebuild adds new variables to Charles Oliveira matchup

Diego Lopes is not simply skipping the final 10 pounds of a featherweight cut. He is rebuilding his preparation around a lightweight debut against Charles Oliveira in the five-round main event of UFC 335 on Dec. 12 in Las Vegas.

BJPenn.com reported that this is Lopes’ first full camp at 155 pounds, with weight training twice a week and creatine added to his routine; Lopes also said he weighed 175 pounds on the morning of his last fight before settling around 170 or 171 after using the bathroom and training.

That changes the betting question. BJPenn.com reported that Lopes has already shown he can carry substantial weight after making 145, but fight-night mass does not establish how he will perform after preparing at the higher limit. The variables are functional: whether added strength improves his ability to resist Oliveira’s takedown chains, whether a less severe cut supports his pace across five rounds, and whether carrying more mass alters the speed and volatility behind his striking.

Lopes brings featherweight durability, but not defensive control

Lopes enters at 28-8 and remains the No. 2-ranked featherweight. His recent form contains two distinct signals. He stopped Jean Silva and Steve Garcia in the second round, but he also completed 10 rounds across two unanimous-decision losses to Alexander Volkanovski. Lopes has never been finished in the 11 bouts in our archive.

That durability matters against Oliveira, whose offensive record creates pressure on both the fight-goes-distance and method-of-victory markets. But Lopes’ survival history should not be confused with airtight defense.

He absorbs 4.65 significant strikes per minute while landing 3.79, with 46 percent striking defense. Across 29 tracked rounds, he has landed 482 significant strikes and scored six knockdowns. His target distribution is heavily tilted toward the head: 349 head strikes, compared with 61 to the body and 72 to the legs.
