Both fighters have been suspended by the CSAC for one year and were fined $2,500 for the failed tests.
Silva, who defeated Justin Eilers via second-round TKO for the newly-created EliteXC heavyweight title at “EliteXC: Unfinished Business” on July 26th, tested positive for the anabolic steroid boldenone. He has been suspended until July 26th, 2009 and is also expected to be stripped of the EliteXC heavyweight title.
Dewees, who was defeated via first-round TKO by Antonio Rogerio Nogueira at “Affliction: Banned” on July 19th, has tested positive for the anabolic steroid nandrolone. He has been suspended until July 19th, 2009.
Both Silva and Dewees can file an appeal with the CSAC.
