UFC Hall of Famer BJ Penn’s erratic behavior has surged into public view once again, this time involving Kayla Harrison amid his latest social media outbursts in early July 2025. Penn posted controversial Instagram messages targeting the newly crowned UFC women’s bantamweight champion at UFC 316, suggesting unfair advantages linked to weigh-in procedures. This unfolding Kayla Harrison UFC retirement controversy has raised alarm among fans and fighters as his accusations remain unproven but deeply unsettling.
Penn’s posts included juxtaposed images of Harrison during official and ceremonial weigh-ins with captions criticizing UFC procedures. One of his remarks bluntly claimed,
“We live in a fantasy world, a world of illusion,”
followed by,
“The masked c— don’t have to take a dr** test or weigh in. What an advantage that is.”
Although his comments weren’t directly hostile toward Harrison, they insinuated suspicions about the integrity of the competition.
He further stated,
“Nothing against Kayla, I’m sure Julianna Pena never weighed in either. BJ Penn weighed in every time. No IV. No PED,”
casting doubt on the legitimacy of others’ weigh-ins compared to his own history. Despite the serious tone, there is no evidence supporting any claims that Harrison or others avoided standard UFC protocols. This unexpected controversy came shortly after Harrison’s major triumph, highlighting a concerning intersection of Penn’s personal turmoil and professional criticism.
Kayla Harrison Contemplated Early Retirement Following Championship Efforts
Just a week after securing her bantamweight title at UFC 316, Kayla Harrison opened up about the emotional toll her career shift had taken. Speaking with UFC analyst Luke Thomas, Harrison revealed the immense pressure she faced and admitted,
“I’m not gonna lie to you. Friday morning, I thought about retiring on Saturday night, it takes a piece of your soul.”
Harrison’s journey to bantamweight was far from straightforward; having dominated lightweight and featherweight in the Professional Fighters League (PFL), the move brought new challenges and risks. Her path to championship was marked by resilience, yet the sudden injection of conspiracy theories involving her weigh-in process has clouded what should have been a celebratory milestone.
The Troubling Context of BJ Penn’s Mental Health and Legal Challenges
BJ Penn’s recent conduct has been marred by a series of alarming events beyond the octagon, contributing to the current turmoil surrounding his statements. Over the past months, Penn has faced multiple arrests in his home state of Hawaii, including a notable May 2025 arrest on domestic abuse charges. His erratic social media posts alleging that family members, including his mother and siblings, have been replaced by imposters, have intensified public concern.
Penn’s mother, Lorraine Shin, responded to his behavior by seeking a restraining order, citing fears for her safety and indicating that Penn suffers from Capgras delusional syndrome, a psychiatric disorder where individuals believe close relatives have been substituted by identical imposters. In legal documents, she asserted,
“I believe my son [B.J. Penn] is suffering from Capgras delusional syndrome [a psychiatric disorder in which a person holds a delusion that a friend, spouse, parent, other close family member has been replaced by an identical imposter].”
Penn has been non-compliant with court rulings, missing scheduled appearances which led to a bench warrant. Upon his subsequent arrest, he attributed his absence to an infection. Currently, Penn faces multiple misdemeanor charges related to these incidents and ongoing court order violations.
Concerns Over Long-Term Effects of Brain Trauma in MMA Fighters
With growing awareness of repetitive head trauma in mixed martial arts, there is increasing speculation about the possible role of chronic traumatic encephalopathy (CTE) in BJ Penn’s recent psychological decline. While no formal diagnosis has been made public, his symptoms—paranoia, delusions, and cognitive impairments—mirror those commonly associated with CTE.
Once celebrated as a fearless competitor and a “warrior” of the sport, Penn’s current struggles underline the complicated and painful reality many fighters face after years of physical combat. This deepening mental health crisis adds a layer of tragedy to his legacy, raising urgent questions about fighter care and awareness within MMA.
The Broader Impact of the Controversy on Kayla Harrison and UFC

As UFC fans and officials watch developments unfold, there is growing hope that Harrison will remain steadfast in her career while the MMA community addresses the mental health challenges faced by its veterans. Ultimately, the sports world must balance respect for legendary fighters like Penn with accountability and support systems that protect all athletes’ well-being.
