Javier Mendez says he noticed Conor McGregor was “off” before injury at UFC 329

Conor McGregor’s attempt to return in earnest at UFC 329 took a decisive turn almost as soon as it began. Javier Mendez, McGregor’s longtime head coach, said he sensed something was not right with the way McGregor looked in the moments leading up to the fight. According to Mendez’s account, McGregor did not carry the same relaxed swagger he expected to see, and that visual read preceded an injury that ended his night quickly.

The comeback fight was against Max Holloway, and the injury was severe. McGregor, listed at 22-7 in MMA and 10-5 in the UFC at the time of the report, tore his ACL and meniscus from what was described as the first kick he threw in the bout. Mendez’s comments place the problem early, suggesting the issue was not cumulative or gradual, but instead surfaced immediately as McGregor began to exchange on the feet.

The timing adds to the storyline of McGregor’s long road back to competition. The report tied his UFC 329 appearance to a longer absence after he had not fought since breaking his leg in July 2021. For a fighter returning after a major lower-body injury, regaining movement confidence, timing, and explosiveness is often as important as conditioning, and an early ACL tear can erase those planned adjustments before they have a chance to stabilize.

Holloway, McGregor’s opponent, entered the night with a strong UFC track record, and the report described him with a record of 28-9 in MMA and 24-9 in the UFC. That context matters because Holloway is known as an active, high-output opponent, and the style requires constant defensive and offensive recalculation. If the knee fails in the opening exchanges, it not only changes the fighter’s game plan, it can remove the ability to absorb pressure and reset distance, even when the initial intention is to set the pace.

Mendez’s characterization of McGregor looking “off” is also notable because it frames the injury as more than a bad break in the moment. Trainers and corners do not see cartilage and ligaments, but they do observe movement qualities such as balance, foot placement, and readiness. In this case, Mendez suggested the look and feel were inconsistent enough to stand out to him before the first kick, which is why his reaction has become part of how the incident is being understood.

UFC 329 is, in the broad sense, the kind of stage where a successful comeback can reshape narratives quickly. A night that ends with an immediate ACL and meniscus tear instead shifts the story toward recovery timelines, training structure, and how a fighter rebuilds confidence in the specific motion patterns that were interrupted. For fans and for McGregor’s future, what follows will likely be defined as much by medical steps and rehabilitation progress as by what was promised at the weigh-in and staredown.

If there is a point to watch next, it is how Mendez and the UFC handle the practical realities of a return after ACL-type injuries. The question becomes less about whether McGregor can still compete at a high level, and more about when he can do so with the same willingness to plant, pivot, and throw power. The injury at UFC 329 turned a comeback bid into an urgent reset, and the next chapter is expected to focus on whether the body and the timing can match the ambition again.
