The Nevada Athletic Commission's complaint was filed after Gilbert stopped Charles Howe in the first round of their Sept. 21 fight in Reno and allegedly tested positive for the substances.

Gilbert said he received a notice in the mail Wednesday that the complaint had been amended.

The allegations regarding the steroid and the other four substances remain are expected to come up at a disciplinary hearing to be scheduled for sometime in January.

"We see the importance of this as acknowledgment that there was no evidence he took methamphetamine whatsoever," Gilbert's attorney, said Mark Schopper, said on Thursday.

The commission dropped the methamphetamine allegation after a negative test on a B sample conducted at the University of Utah Center for Human Toxicology. The original positive test on the A sample had been conducted by Quest Diagnostic.

"The labs had disagreed," Mark Kizer, the commission's executive director said. "As I mentioned before, the tie goes to the fighter. I'm waiting to get the steroid test back from Utah. I figure there's no need to wait for dropping the meth with the two labs in disagreement."

Gilbert, who appeared on the NBC reality series "The Contender," said the methamphetamine allegation affected all aspects of his life.

"It was the most devastating thing in the world to be accused of using methamphetamine," Gilbert said. "The way that was pitched to the media was that I was using it to cut weight. It was terrible. I can't imagine being accused of anything worse.

"I've always denied knowingly using illegal substances from day one," Gilbert said.

Gilbert, who also is a boxing promoter, said the methamphetamine allegation caused sponsors to drop him.

"The destruction that allegation caused to my life and career is absolutely beyond words," Gilbert said. "I was scheduled to go overseas on a USO Tour and go back to Iraq. I haven't heard from those people again. There were three or four companies we were in negotiation with and just about ready to cement something.

"We had two or three fights that were set up. There's a lot of things that went down that are gone. An amended complaint isn't going to do anything for me. It has been a nightmare."

Gilbert said he looks forward to answering the remaining allegations in front of the commission members in January. The commission's complaint contains allegations that Gilbert tested positive for the steroid, amphetamine, nordiezepam, oxazepam and temazepam, all of which are banned by the commission.

He said the amphetamine, nordiezepam, oxazepam and temazepam were medications prescribed to him that he reported to the commission.
