Raymundo Beltran fails drug test
Mexico's Raymundo Beltran tested positive for the anabolic steroid stanozolol following his bout with Takahiro Ao on May 1 in Las Vegas.
The 33-year-old fighter faces a disciplinary hearing in front of the commission and will likely be suspended and fined.
Beltran was scheduled to challenge for the vacant WBO lightweight title against Ao, however he came in over the 135lb weight limit so only his Japanese opponent was eligible to win the belt. Beltran scored a second-round knockout and the title remained vacant.
He was due to fight countryman Humberto Soto on June 27 but that bout has now been canceled.
