EUGENE, Ore. (AP) — Banned sprinter Justin Gatlin lost his appeal to run in the U.S. Olympic track trials Thursday and said he will end that effort rather than take the case to the Supreme Court.

In a briefly worded decision, the 11th U.S. Circuit Court of Appeals in Atlanta ruled Gatlin hasn't 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 100-meter champion 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
