Two Denver Broncos players are suing the NFL seeking to overturn their drug suspensions.
The lawsuit filed in Denver District Court contends the league violated protocol in collecting urine samples from linebacker D.J. Williams and defensive lineman Ryan McBean and refused to clear the players after the collector was fired for not following proper procedures.
Williams and McBean were suspended without pay for Denver's first six games of the 2012 season.
Williams' lawyer, Peter R. Ginsberg, said the league contends the urine samples they provided to an NFL specimen collector for testing in August weren't from a human. Ginsberg said the specimen collector said he watched Williams void directly into the specimen bottle, so it would've been impossible for the specimen to be non-human.
