Both main-event fighters successfully made weight. Allen registered 186 pounds, while Duncan came in at 185 pounds. The non-title middleweight limit allows fighters to weigh up to 186 pounds.

UFC Vegas 122 Main Card Weigh-In Results

The main card includes five fights across the middleweight, lightweight, strawweight, featherweight and bantamweight divisions. Souza was the only main-card fighter who failed to meet her weight requirement.

UFC Vegas 122 Preliminary Card Weigh-In Results

The preliminary card features seven matchups, with Bonfim and Ribeiro responsible for the two weight misses outside the main card.

Both fighters exceeded their respective divisional limits, resulting in financial penalties. Their opponents successfully completed the weigh-in process.

Ismael Bonfim Misses Lightweight Limit by 7.5 Pounds

Ismael Bonfim delivered the biggest surprise of Friday’s weigh-ins when he stepped on the scale at 163.5 pounds. The Brazilian exceeded the non-title lightweight limit of 156 pounds by 7.5 pounds.

His opponent, Francisco Prado, weighed 155 pounds and comfortably cleared the limit. The difference between their official weigh-in figures reached 8.5 pounds, creating a significant disparity ahead of the scheduled matchup.

The UFC confirmed that Bonfim would forfeit 25% of his purse to Prado. The bout remained on the event lineup despite the substantial weight miss.

Bonfim’s Third UFC Weight Miss Raises Questions

Friday’s result marked the third time Bonfim had missed weight during his UFC career. His previous problems occurred before scheduled fights against Vinc Pichel in November 2023 and Chris Padilla in November 2025.

Bonfim missed the limit by 3.5 pounds ahead of the Pichel matchup. He later came in five pounds heavy for his scheduled fight against Padilla.

His latest miss represents an even larger failure to meet the lightweight requirement. The repeated problems raise questions about whether he can consistently compete at 155 pounds.

Ketlen Souza Misses Weight Ahead of Loopy Godinez Fight

Ketlen Souza also failed to make weight for her women’s strawweight matchup against Loopy Godinez. Souza registered 117 pounds, one pound above the permitted non-title limit of 116 pounds.

Godinez successfully made weight at 115.5 pounds. The UFC confirmed that Souza would surrender 20% of her purse to her opponent.

Although Souza’s miss was considerably smaller than Bonfim’s, it still represented a failure to meet the agreed weight requirement. Their three-round matchup remained scheduled for the main card.

What Does Souza’s Weight Miss Mean for the Fight?

The fight can proceed under the agreed conditions despite Souza weighing above the strawweight allowance. Her financial penalty compensates Godinez for accepting the matchup under those circumstances.

However, the difference on the scale does not automatically determine how the fight will unfold. Both athletes must still complete their preparation before entering the Octagon.

Godinez will look to use her wrestling and pressure against Souza’s striking. Their matchup remains an important contest on Saturday’s main card.

Brendson Ribeiro Comes in 2.5 Pounds Heavy

Brendson Ribeiro became the third fighter to miss weight after registering 208.5 pounds for his light heavyweight matchup against Felipe Franco.

The non-title light heavyweight limit stands at 206 pounds, leaving Ribeiro 2.5 pounds over the permitted maximum. Franco successfully made weight at 205 pounds.

The UFC confirmed that Ribeiro would forfeit 20% of his purse to Franco. Their preliminary-card contest remained scheduled despite the missed weight.

Ribeiro’s situation added to an unusual weigh-in session in which three fighters failed to meet their respective divisional requirements.

Brendan Allen and Christian Leroy Duncan Make Weight for Main Event

Brendan Allen and Christian Leroy Duncan avoided any complications during the official weigh-ins. Allen registered 186 pounds, while Duncan came in one pound lighter at 185.

Allen enters the main event with three consecutive victories. Duncan has won five straight fights and will compete in his first UFC headliner.

The matchup offers both middleweights an opportunity to strengthen their positions in the division. Allen has more experience against established contenders, while Duncan enters with considerable momentum.

Why Allen vs. Duncan Matters for the Middleweight Division

Allen has remained among the leading middleweight contenders through victories over experienced opponents. Another win could move him closer to a major divisional matchup.

Duncan, meanwhile, has an opportunity to secure one of the most important victories of his career. Defeating an established contender in a five-round main event would strengthen his championship ambitions.

The outcome could influence the UFC middleweight rankings as the promotion considers future matchups.

Both fighters successfully completing their weigh-ins ensures that the headliner can proceed without any weight-related complications.

Three Fighters Face Purse Penalties at UFC Vegas 122

The UFC confirmed financial penalties for all three fighters who missed weight. Each penalty involves transferring a percentage of the offending fighter’s purse to the opponent.

Bonfim received the largest penalty after recording the most significant miss. Souza and Ribeiro each forfeited 20% of their purses.

The penalties allow the affected opponents to receive additional compensation for accepting fights against competitors who exceeded their agreed weight limits.

What Happens When a UFC Fighter Misses Weight?

UFC fighters must meet the weight limit for their contracted division. In non-title fights, most athletic commissions allow a one-pound allowance above the division’s standard limit.

When a fighter exceeds that allowance, the bout may continue if the athletic commission approves the arrangement and the opponent agrees to proceed.

The fighter who misses weight commonly forfeits part of their purse. The amount depends on the circumstances and the terms established for the matchup.

However, a significant weight miss can also lead to a cancellation. The commission and promotion must consider safety before allowing a contest to proceed.

Weight-related complications are among the reasons UFC fights can be canceled shortly before an event.
