ATLANTA — A federal court has denied sprinter Justin Gatlin's appeal to run in the U.S. Olympic track trials this weekend.

The 11th U.S. Circuit Court of Appeals said today that Gatlin has not shown he meets the "applicable standard for such an injunction."

Earlier this month, the Court of Arbitration for Sport upheld a four-year ban against Gatlin for doping violations, but the defending Olympic champion in the 100 meters went to federal court seeking to run in trials starting Saturday.

He said he had been discriminated against under the Americans with Disabilities Act because his first doping violation was for taking prescribed medication to treat attention deficit disorder.

The U.S. Olympic Committee and the U.S. Anti-Doping Agency argued that federal courts did not have jurisdiction In the case, an argument U.S. District Judge Lacey Collier agreed with Tuesday when he withdrew the temporary restraining order he had originally granted the week before.

Gatlin sought an emergency injunction from the appeals court, but was denied.

Messages left by The Associated Press with his attorney, Joe Zarzaur, weren't immediately returned.
