Heavyweight Tim Persey (Pictures) of Irvine, Calif., tested positive for methamphetamine following his stoppage loss to Jonathan Wiezorek (Pictures) last Saturday, the Los Angeles Times reported.

Persey, who was a replacement for Antonio Silva (Pictures) after the Brazilian fell off the FEG-promoted card due to medical concerns stemming from testing done by the California State Athletic Commission, faces a $1,000 fine and a six-month suspension.

"Mr. Persey has 30 days from the date on his suspension letter to appeal the suspension in writing and request a hearing before the California State Athletic Commission," said CSAC representative Bill Douglas.
