Subriel Matias Doping Controversy: Title Reign in Jeopardy After Positive Test for Ostarine
Is Subriel Matias’s WBC junior lightweight title on teh verge of being stripped? A recent positive drug test has thrown the boxing world into turmoil, casting a shadow over the planned January 10th defense against Dalton Smith. This article provides a complete breakdown of the situation, exploring the implications for Matias, Dalton smith, the WBC, adn the broader landscape of boxing anti-doping efforts.
Subriel Matias, the current WBC junior lightweight champion, is facing a potential crisis after testing positive for ostarine, a prohibited substance, according to a Voluntary Anti-Doping Association (VADA) test. the revelation, first reported by Ring Magazine, comes just weeks before his scheduled title defense against Dalton Smith in Brooklyn, raising serious questions about the future of his championship reign.
The Positive Test & Initial Reactions
The positive test for ostarine – a Selective Androgen Receptor Modulator (SARM) frequently enough used for building muscle mass - was confirmed by a source to ESPN. Mauricio Sulaiman, President of the WBC, swiftly addressed the situation, stating, “The WBC has received notification from VADA about an adverse finding from a test performed by WBC super lightweight champion Subriel Matias. The WBC has begun the investigation process as per the Clean Boxing Program protocol. I have spoken to our champion Subriel and his Promoter Mr Orengo, and they have expressed their absolute availability and cooperation as the process unfolds.”
Matias’s team has indicated they will request a test of his B-sample, a standard procedure in these cases. As of now, they have declined to comment further pending the B-sample results. The deadline for this request is December 1st.
What is Ostarine and Why is it Banned?
Ostarine, while sometimes marketed as a research chemical, is banned by the World Anti-Doping Agency (WADA) and most major boxing organizations, including the WBC.SARMs like ostarine mimic the effects of testosterone, promoting muscle growth and enhancing recovery. However, they carry important health risks, including cardiovascular problems and hormonal imbalances. Their use violates fair play principles in sport.

Implications for Matias and the January 10th Fight
The consequences for Matias could be severe. A positive B-sample will almost certainly lead to the cancellation of his fight against Dalton Smith. More critically, it could result in the revocation of his WBC junior lightweight title.
This isn’t the first time ostarine has surfaced in a high-profile boxing case. In 2024, Ryan Garcia tested positive for the same substance following his fight with Devin Haney. The New York State Athletic Commission (NYSAC), which will oversee the matias-Smith bout, overturned Garcia’s win to a no-contest and imposed a one-year suspension. This precedent suggests a similar outcome is absolutely possible for Matias.
What Happens Next? A Step-by-Step Breakdown
- B-Sample Analysis: Matias’s team will request and await the results of the B-sample analysis.This is a crucial step to verify the initial finding.
- WBC Investigation: The WBC’s Clean Boxing Program will conduct a thorough investigation, gathering details from Matias, his team, and VADA.
- NYSAC Hearing: The New York State Athletic Commission will likely hold a hearing to determine the appropriate disciplinary action, should the B-sample confirm the initial positive test.
- Potential Sanctions: Possible sanctions include:
* Fight Cancellation: The January 10th bout against Dalton Smith will almost certainly be cancelled.* Title Stripping: The WBC could strip Matias of his junior lightweight title.
* Suspension: Matias could face a suspension from boxing, possibly lasting a year or longer.* Fine: A financial penalty could be imposed.
- Dalton Smith’s Future: If Matias is stripped of the title, the WBC will determine the next steps for the junior lightweight division, potentially elevating dalton Smith to champion or ordering a tournament to determine a new titleholder.
