Banned European 100 metres record holder Dwain Chambers has no intention of returning to athletics, according to his management.
Chambers tested positive for the designer steroid tetrahydrogestrinone (THG) in an out-of-competition sampling in August.
The B sample also tested positive, and he was banned for two years from November. His appeal was rejected in February, and he was given the right of appeal to the Court of Arbitration for Sport in Switzerland.
Jonathan Barnett, chairman of The Stellar Group, told the Financial Timesthat he could not "see a way back into athletics" for Chambers.
"He's sickened by the whole thing," Barnett said. "We are also sickened by what's happened to him. He's disillusioned. At the moment he has no intention of coming back into athletics."
Barnett confirmed a switch to American Football was one possibility for Chambers.
"Where he goes in the end, I don't know, the NFL is a possibility," he said. "There are a few other things we are looking at, personality-wise, TV-wise. He needs to get away for a while, basically lie on a beach, and figure out what to do."
