Diego Lopes Wants a War With Oliveira — UFC 335 Could Change His Entire Future
GOATIFYDiego Lopes has been handed the kind of fight that can change the direction of a career in one night. On December 12 in Las Vegas, the Brazilian will challenge Charles Oliveira for the BMF belt in the UFC 335 headliner. The pairing already promised action. Lopes has now made the invitation unmistakable: he wants Oliveira to meet him in the middle and trade.
That is an entertaining promise, but it is also a fascinating risk. Oliveira has built a career on turning opponents’ aggression into submissions, and his most recent BMF victory came from controlling Max Holloway rather than engaging in the sort of stand-up firefight the belt’s mythology suggests. Lopes, meanwhile, is moving into a new weight class after spending years chasing featherweight gold. A spectacular win would give him instant leverage at 155 pounds. An undisciplined exchange could make him pay for skipping the slow climb.
The most important question is not whether these two can produce a memorable fight. It is whether Lopes can get the kind of fight he wants without giving Oliveira exactly the openings he needs.
Lopes is inviting the kind of chaos he usually creates
Lopes did not present the December main event as a cautious opportunity to score points. In his latest comments, he welcomed the idea that Oliveira might feel obliged to make up for criticism of his grappling-heavy win over Holloway. Lopes hopes that frustration produces an aggressive opening, because an exchange of heavy punches is precisely the contest he believes he can win. It is an unusually direct challenge from a fighter who has rarely needed much encouragement to accelerate a fight.
His record of seven performance bonuses in ten UFC appearances helps explain the confidence. Lopes has become an attraction by creating moments rather than patiently managing every minute. Even when the first phase of a fight goes against him, he tends to retain the belief that one hard connection can change everything. Against Steve Garcia at the June 2026 UFC Freedom 250 event, he endured early trouble before stopping Garcia in the second round. The comeback was a reminder that he can survive a difficult spell and still generate a finish without needing to win every exchange.
But the Garcia result also shows why a blanket promise of violence is not a complete game plan. Oliveira is not merely a striker who will stand in front of him and trade until someone falls. The former lightweight champion can punch into a clinch, turn a missed shot into a body lock, or attack a neck as soon as an opponent changes levels. The more committed Lopes becomes to ending an exchange with a knockout, the more important his balance and defensive positioning become.
There is a subtle psychological contest already taking place. Lopes is trying to make a patient Oliveira look as though he has something to prove to the crowd. Oliveira’s best response may be to ignore that invitation entirely. For Lopes, the winning version of aggression will be pressure with exits, not pressure that leaves his hips, neck and back available every time he throws.
Oliveira already proved the BMF belt does not require a stand-up war
The debate around the BMF belt often treats entertainment as a technical requirement. Oliveira’s March win over Holloway exposed the flaw in that assumption. He took Holloway down repeatedly, advanced position, threatened submissions and controlled the pace for five rounds. All three judges scored it 50-45. Some spectators wanted a striking duel; Oliveira delivered a comprehensive demonstration of how dangerous a complete mixed martial artist can be when he refuses to fight on someone else’s terms.
That matters because the belt is not a separate rule set. There is no obligation to keep the contest standing or to abandon a dominant position for the sake of spectacle. Oliveira earned the title by using the most effective tools available to him. He can still hurt opponents on the feet, but his biggest advantage is the way his striking, clinch entries and submission threats connect. A defensive mistake that might cost a fighter a few seconds against another opponent can become an immediate finishing sequence against Oliveira.
Lopes has acknowledged that danger rather than dismissing it. He regards Oliveira as his toughest assignment yet, precisely because the veteran can end a fight from several positions. Lopes also insists that being put on his back does not mean he will spend the rest of a round merely waiting to survive. That is the right attitude for an ambitious challenger, but it must be backed by positional choices: when to scramble, when to protect a wrist, when to concede a harmless position and when to refuse a transition.
Oliveira’s apparent dilemma is therefore smaller than it looks. If Lopes gives him an opportunity to strike cleanly, he can take it. If Lopes overcommits and presents a takedown or submission entry, Oliveira can follow the same path that worked against Holloway. The pressure to entertain is real, but it is external. Inside the cage, the challenger is the one who has to solve both versions of Oliveira.
The BMF title may be marketed through the language of fearlessness. In practice, December could be decided by who is willing to look less reckless for just long enough to create the decisive opening.
The move to 155 pounds is a career reset, not a one-fight experiment
Oliveira was not the original destination for Lopes’ first lightweight campaign. After his victory over Garcia, Lopes was lined up for a move to 155 pounds, with Dan Hooker discussed as an opponent in Paris. That route changed when Salahdine Parnasse entered the picture against Hooker. Another possible pairing with Benoit Saint Denis was considered before the UFC ultimately offered the December BMF headliner. The sequence reveals how quickly a contender’s path can change when an opportunity becomes available at a higher weight.
For Lopes, the jump is not simply about having an easier cut. He says he has been adding size since June and now walks around 180 pounds, noticeably heavier than his usual position at the same stage of a featherweight camp. That extra mass can help him absorb the demands of clinching and grappling with established lightweights. It may also change the rhythm of his offense: how long he can sustain bursts, how efficiently he moves after a scramble and how much punishment his combinations carry against naturally larger opponents.
Those are questions that cannot be answered by the number on a scale alone. Oliveira has spent years facing elite 155-pound fighters and knows how to make an opponent carry weight in grappling exchanges. Lopes will need to show that his physical development has improved his ability to hold position and defend transitions, not merely made him look bigger between camps. His first test at the weight is unusually severe because it is also a five-round main event against one of the division’s most accomplished finishers.
The longer-term decision is just as consequential. Lopes has left open the possibility of returning to featherweight, but he has made clear that a return would need to offer something meaningful. Two losses to Alexander Volkanovski make another immediate route to that championship complicated. At lightweight, by contrast, a victory over Oliveira would create a new résumé almost overnight. It would also force Lopes to commit to building momentum rather than bouncing between divisions every time the rankings shift.
That is why the December bout carries more weight than a ceremonial BMF defense. It can establish whether Lopes belongs among the elite at 155 pounds or whether he still has important adjustments to make before a full lightweight campaign.
A win could make Lopes a contender — but Gaethje remains an uncertain destination
Justin Gaethje sits at the top of the lightweight division after his extraordinary win over Ilia Topuria at UFC Freedom 250 in June. Yet the immediate championship picture is unsettled. Gaethje is not expected to defend the undisputed belt again in 2026, and retirement has remained part of the conversation. That leaves contenders with an unusual problem: there is a champion to chase, but no simple timetable that tells them when a title opportunity will arrive.
Lopes has been careful not to present a BMF win as an automatic ticket to the undisputed championship. He sees the potential appeal of facing Gaethje, whose willingness to engage could make for an enormous event, but acknowledges that matchmakers might still choose another direction. Arman Tsarukyan remains a serious part of the contender conversation, and Topuria’s future will influence the division once he returns. A spectacular December result would strengthen Lopes’ argument; it would not erase every other claim.
There is a tactical reason the Gaethje idea is attractive. Lopes can offer a high-output striking battle without arriving with the same established reputation for relentless takedowns that makes some other opponents so difficult to prepare for. That does not mean Lopes lacks grappling. It means a potential Gaethje matchup could be sold around mutual willingness to exchange, a simpler proposition for a fighter whose reputation has long rested on spectacular violence.
Still, the best argument Lopes can make for the next step is not a promise about the next fight. It is a disciplined performance against Oliveira. If he beats a proven former champion who is dangerous on the feet and on the mat, he will have shown more than entertainment value. He will have demonstrated that his offense translates to the new division and that his defense survives the most punishing types of transition.
Conversely, if Oliveira takes advantage of the challenger’s desire to entertain and dominates with control or submissions, the lightweight rankings will have a very different story to tell. Oliveira could move closer to another undisputed title opportunity, and Lopes would face a choice between rebuilding at 155 pounds or reconsidering featherweight.
The belt at stake in December is the BMF title. The bigger prize for Lopes is control over what comes after it.
Lopes has turned UFC 335 into a challenge with two layers. The first is personal: can he force Oliveira into the open exchanges he loves without sacrificing the defense that keeps him alive against a world-class submission specialist? The second is strategic: can he make his lightweight debut so convincing that the UFC has to consider him for the division’s biggest fights?
Oliveira does not need to accept a brawl to prove he belongs in the headliner. Lopes does not need to abandon his aggression to prove he belongs at 155 pounds. The fighter who best understands that distinction may be the one who leaves Las Vegas with the BMF belt — and with a much clearer future.
