Did the NFL violate any law due to suspensions of D. J. Williams and Ryan McBean?

The National Football League sentenced to bans the linebacker D. J. Williams and Ryan McBean, a defensive lineman, of the team Denver Broncos for violation of steroid policy. They were suspended from 6 games. But they were not banned for intake of steroids. They didn’t test positive for steroids or other forbidden medications. They were accused in providing “non-human” urine samples to the drug testing officer.
D. J. William confirmed that he had never tested for any forbidden product during 8 years of his career. The football player added that he was proud of his records. The linebacker of the NFL noted that he was also proud of his manner in that he conducted himself, being an athlete.
The attorney for McBean, Peter Shaffer, affirmed that the NFL had violated rights of this player. He noted that since McBean had never tested positive for any prohibited medicine, the NFL didn’t have any right to sentenced him to ban.
Peter Schaffer confirmed that he wanted to make it clear that neither D. J. Williams, nor Ryan McBean tested positive for forbidden substances.
A lawsuit was filed in Denver County Court against suspensions of these players of the NFL.
D. J. Williams and Ryan McBean affirmed that the drug testing officer had violated several rules related to the procedure of collecting urine samples.
Peter Schaffer noted that certain similarities had been between his client and Ryan Braun. Braun won his appeal connected with his suspension from 50 games for application of testosterone. Ryan Braun could prove that Dino Laurenzi, the drug testing officer, violated steroid policy.
As for Laurenzi, different anti-doping agencies defended and supported him. The WADA also supported Dino Laurenzi. It was said that there was the same procedure of collecting and sending urine samples not only for the MLB but also for the WADA.
But as for the drug testing officer that collected samples of Williams and McBean, another attitude was displayed to him. He was fired by the NFL for wrong doing his duty.
At the hearing the NFL administrators admitted that the drug testing officer violated the rules linked with collection of urine samples.
Nevertheless, the appeal on behalf of the football players was rejected.
