A federal appeals court has backed the NFL over the performance-enhancing drug suspension of Denver Broncos linebacker D.J. Williams. In an unsigned ruling, a three-judge panel of the 10th Circuit Court of Appeals upheld Williams' six-game ban, saying that it is not the court's place to intervene in this kind of employment dispute. "[A] court's role in these types of arbitration cases is simply to determine whether the arbitrator strayed from the collective-bargaining agreement," the judges wrote. Williams' suspension stems from a failed urine test taken last August. Drug testers found no naturally produced testosterone in the sample Williams provided, leading them to conclude that the urine sample wasn't human. In a November test, the specimen collector reported that Williams turned away during the test and had a suspicious bottle fall to the ground from his waist area. Source: Denver Post
