Mayfield has until late June to file an appeal to the US Supreme Court, but he has indicated he will move on from the case.
Mayfield was disputing the accuracy of a drug test he failed in May of 2009 , which the sanctioning body said revealed that Mayfield took methamphetamines.
Mayfield claims the failed drug test was the result of a mixture of Adderall and over-the-counter Claritin D.
Mayfield also faces four counts of felony larceny stemming from a February indictment that states he was in possession of stolen property.
Mayfield also recently lost his home to foreclosure. He has 10 days to move out of the house, and may still be forced to pay $500,000.
The 400-acre property was sold at auction and Carolina Farm Credit, the bank that made the loan to Mayfield, was the only bidder. Another buyer has 10 days to make an offer. If no other offer is made, Mayfield must leave the premises on May 10.
