The league and the NFL Players Association announced an agreement on a new drug policy on Sept. 19 that included HGH testing for the first time ever.
"As you know, the new Performance Enhancing Substances Policy includes HGH testing. Testing for HGH will begin on Monday, October 6th," NFLPA president Eric Winston wrote in a letter to players. "Each week of the season, 5 players on 8 teams will be tested. No testing will occur on game days. We negotiated to ensure that the methodology of testing be conducted in the most professional and safest manner for players. Importantly, after three years of negotiating, players won the right to challenge any aspect of the science behind the HGH isoforms test in an appeal of a positive test."
It also stated that any positive test violations of both substances of abuse and performance enhancing drug policies -- which includes HGH -- will be handled by an independent arbitrator.
