Gatlin appeals four-year ban
Olympic sprint champion Justin Gatlin has appealed his four-year doping suspension.
He is attempting to return to competition for the Beijing Games in August.
The notice was filed yesterday to the Court of Arbitration for Sport, the international body that has the final say in such matters.
A U.S. arbitration panel earlier this month reduced the 25-year-old sprinter\'s potential eight-year ban to four.
Gatlin tested positive for excessive levels of testosterone at the Kansas Relays in 2006, his second doping offense.
The first came in 2001 when Gatlin tested positive for amphetamines, part of a prescribed medication he was taking for attention deficit disorder.
Gatlin wants the first offense erased.
That would make Gatlin\'s 2006 case his first offense, clearing the way for a further reduced ban.
