UFC heavyweight Mohammed Usman has been suspended for 30 months following a positive drug test for testosterone, a decision that has drawn significant attention across the mixed martial arts community.
The suspension was officially announced by the Combat Sports Anti-Doping (CSAD) on Thursday, confirming that the violation occurred during an out-of-competition test conducted in September.
Usman, who holds a professional MMA record of 11 wins and 4 losses, is the younger brother of former UFC welterweight champion Kamaru Usman.
The case has not only impacted Mohammed Usman’s career but has also reignited discussion around anti-doping enforcement in the Ultimate Fighting Championship.
This article breaks down the full timeline of events, the substances involved, CSAD’s ruling, and what the suspension means for Usman’s future in the UFC.
Positive Testosterone Test Leads to Immediate Action
According to CSAD’s statement, Mohammed Usman tested positive for testosterone during an out-of-competition drug test.
Testosterone is a prohibited substance under UFC anti-doping rules when used exogenously, as it can provide unfair advantages related to strength, recovery, and endurance.
Following the positive test result, Usman was immediately removed from his scheduled bout against Valter Walker.
At the time, the UFC had not publicly detailed the reason for his withdrawal, but CSAD’s announcement has now clarified the circumstances.
Out-of-competition testing is considered one of the most important tools in anti-doping programs, as it helps prevent athletes from using banned substances during training camps rather than fight week. A positive result in such tests is treated seriously and often leads to lengthy suspensions.
Admission of Testosterone and BPC-157 Use
CSAD further revealed that Mohammed Usman later admitted to using testosterone intentionally. In addition to testosterone, he also acknowledged the use of a prohibited peptide known as BPC-157.
BPC-157 has gained attention in recent years within combat sports circles due to claims that it aids in injury recovery and tissue repair.
However, it is listed as a banned substance because of its potential performance-enhancing effects and lack of approval for athletic use.
Usman’s admission confirmed that the presence of these substances was not accidental.
Under CSAD rules, intentional use typically carries a standard suspension of two years for a first offense involving anabolic agents such as testosterone.
False Statements Lead to Extended Ban
What ultimately extended Mohammed Usman’s suspension beyond the standard two-year period was his conduct during the investigation.
According to CSAD, Usman initially provided false explanations regarding the presence of the banned substances.
The agency stated that Usman attempted to mislead investigators before eventually admitting to the violations.
Due to this attempt to deceive the testing authority, CSAD added six months to the standard suspension period. This brought the total ban to 30 months.
CSAD emphasized that honesty and cooperation during an investigation are critical factors in determining sanctions.
Athletes who provide false statements risk harsher penalties, even if they later come forward with the truth.
Suspension Timeline: Start and End Dates Confirmed
The 30-month suspension has been applied retroactively. CSAD confirmed that the ban officially began on October 9, 2025, and will remain in effect through April 9, 2028.
During this period, Mohammed Usman is prohibited from competing in UFC bouts or participating in any sanctioned events under the UFC anti-doping program.
He is also restricted from certain forms of training and access to UFC facilities, depending on the terms of the suspension.
By the time the ban concludes, Usman will be approaching his late 30s, a critical factor in a division where physical conditioning and durability are essential.
Mohammed Usman’s UFC Career So Far
Mohammed Usman fights out of Florida and gained mainstream attention as a contestant on The Ultimate Fighter.
His time on the show helped introduce him to a broader audience, particularly given the connection to his championship-winning brother.
Since joining the UFC roster, Usman has compiled a 4-3 record inside the Octagon. Competing in the heavyweight division, he has been known for his physical strength and aggressive fighting style.
While he has shown flashes of potential, consistency has been a challenge. The suspension now places his momentum on hold at a crucial stage of his career.
Impact on the Heavyweight Division
The UFC heavyweight division is one of the most competitive and physically demanding categories in the sport. Extended time away from competition can significantly affect a fighter’s ranking, conditioning, and relevance.
For Mohammed Usman, the suspension means losing nearly two and a half years of potential fight opportunities.
During that time, new prospects will emerge, and established contenders will continue to separate themselves.
When Usman becomes eligible to return in 2028, he will likely need to rebuild his position from the ground up, possibly facing unranked or rising opponents as he works his way back into contention.
UFC and CSAD’s Stance on Anti-Doping
This case highlights the strict enforcement approach taken by the UFC and CSAD toward anti-doping violations.
Since the introduction of independent testing programs, the promotion has consistently stated that fighter safety and fair competition are top priorities.
Testosterone-related violations have historically resulted in lengthy suspensions, particularly when intent is established.
CSAD’s decision to add extra time due to false statements reinforces the message that cooperation is expected from all athletes under investigation.
The UFC has not issued a separate statement beyond acknowledging CSAD’s ruling, but the organization has consistently supported sanctions handed down by its anti-doping partners.
Reaction Within the MMA Community
News of Mohammed Usman’s suspension has sparked mixed reactions among fans and analysts. Some have expressed disappointment, noting the opportunity he had to establish himself in the UFC heavyweight division.
Others have pointed out that the rules regarding banned substances are clear and that intentional use, combined with misleading investigators, leaves little room for leniency.
The involvement of a prohibited peptide alongside testosterone has also raised concerns, as peptides have become an increasing focus of anti-doping efforts across combat sports.
Comparison With Other UFC Doping Cases
Over the years, several UFC fighters have faced suspensions for similar violations involving anabolic agents or recovery-related substances. In many cases, cooperation with investigators has resulted in reduced penalties.
Mohammed Usman’s situation stands out because the suspension exceeded the standard duration due to his initial false statements.
CSAD has previously stated that honesty during the process can significantly influence final sanctions.
This case serves as a reminder that attempting to conceal violations often leads to worse outcomes than early disclosure.
What Comes Next for Mohammed Usman?
For now, Mohammed Usman’s focus will likely shift away from competition and toward compliance with the terms of his suspension.
Fighters serving lengthy bans often use the time to address physical issues, refine skills, and plan for a potential comeback.
However, returning after a 30-month absence will not be easy, especially in the heavyweight division where timing, conditioning, and durability play major roles.
Whether Usman can successfully return to the UFC after April 2028 remains uncertain. Much will depend on his commitment during the suspension period and the opportunities available upon his reinstatement.
Final Thoughts
The 30-month suspension of Mohammed Usman marks a significant moment in his MMA career.
A positive testosterone test, admission of using banned substances, and attempts to mislead investigators combined to produce one of the longer suspensions seen in recent UFC history.
With the ban running until April 2028, Usman faces a long road before he can step back into the Octagon.
The case also reinforces the UFC and CSAD’s firm stance on anti-doping and the consequences of violating those rules.
As the heavyweight division continues to evolve, Mohammed Usman’s future remains an open question, one that will only be answered once his suspension comes to an end and he seeks another chance under the UFC banner.
