WBC light welterweight champion Subriel Matias let his followers know that his fight against Dalton Smith is still on for January 10, 2026. Matias (23-2, 22 KOs) says the banned substance he tested positive for, Ostarine, was below the limit. He states that it was contamination.
Matias vs. Smith (18-0, 13 KOs) is still on for DAZN at the Barclays Center in Brooklyn. Subriel says the Ostarine level in his test was 0.085, which was below the sanctionable limit.
Had Matias been stripped of his WBC 140-lb title, #2 Alberto Puello would likely have been the one that the Matchroom-promoted Dalton would have fought for the vacant belt. For Smith, he would have less to worry. Puello isn’t a big puncher and wouldn’t be attacking nonstop the way the heavy-handed Subriel will.
“Listen to me clearly, listen to me clearly! I have never in my life doped, never,” said Subriel Matias on social media, making it clear he never took any banned substance. “I have never put anything in my body, never. I have never cheated anyone, never.
“Everything I’ve accomplished has been with sweat, with pure sweat,” said Matias. They found 0.085… 0.085 nanograms. That’s not even one-tenth of what they sanction you for. The limit is 0.1, and they found 0.085. That’s contamination, that’s not doping.
“I’m clean, I’m clean. I’ve never doped in my life. I’ve never put anything in my body. Everything has been sweat, pure sweat. I swear on my mother, I swear on my children, I swear on everything I love most: I am clean. I’ve never doped, never in my life. That’s contamination.
“The fight is going ahead, the fight is going ahead. I’m clean, I’m clean,” said Subriel.
