Did the NFL violate any law, suspending those who didn’t test positive for forbidden medications?

The National Football League suspended D. J. Williams, a linebacker, and Ryan McBean, a defensive lineman, of the team Denver Broncos for violation of steroid policy. These players were suspended from 6 games. But they were not banned for usage of steroids. They didn’t test positive for steroids or other controlled substances. They were accused in providing “non-human” urine samples to the officer of drug testing.
D. J. William claimed that he had never tested for any banned preparation during 8 years of his career. He added that he was proud of his records. He noted that he was also proud of his manner in that he conducted himself, being a sportsman.
The attorney for McBean, Peter Shaffer, confirmed that the NFL had violated rights of the defensive lineman. He mentioned that since McBean had never tested positive for any forbidden drug, the NFL didn’t have any right to sentenced him to ban.
Peter Schaffer claimed that he intended to make it clear that neither D. J. Williams, nor Ryan McBean tested positive for prohibited preparations.
A lawsuit was filed in Denver County Court against suspensions of these players of the NFL.
The players confirmed that the drug testing officer had violated certain rules connected with the procedure of collecting urine samples.
Schaffer noticed that several similarities had been between his client and Ryan Braun. Braun won his appeal connected with his suspension from 50 games for administration of testosterone. Ryan Braun could prove that Dino Laurenzi, the drug testing officer, violated steroid policy.
As for Laurenzi, he was defended and supported by different anti-doping agencies. The WADA also supported Dino Laurenzi. It was confirmed 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 incorrect doing his duty.
At the hearing the NFL administrators acknowledged that the drug testing officer violated the rules linked with collection of urine samples.
Nonetheless, the appeal on behalf of the players was rejected.
