Memphis, TN -- (Sports Network) - A U.S. magistrate in Memphis has denied Doug Barron's request for a temporary restraining order that would have allowed him to play in the second stage of the PGA Tour qualifying tournament.

In a statement Monday evening, the PGA Tour said it was "pleased with the court's decision" but noted it would not have further comment.

Barron was given a one-year suspension by the PGA Tour for testing positive for a beta-blocker and testosterone, according to court documents.

In documents filed in U.S. District Court in Memphis, it was revealed that the positive tests came during the St. Jude Classic on June 11.

Barron, the first player to receive a suspension since testing began in July 2008, sued the PGA Tour in an attempt to lift the ban.

Court documents show that Barron had previously sought -- and was denied -- therapeutic use exemptions for propranolol, the beta-blocker, and testosterone. The exemptions allow players to use prohibited substances on the basis of their need to treat an illness or condition.

Barron, who has battled injury in a journeyman career on the PGA and Nationwide Tours, did not dispute the results of his positive tests.
