The NFL and the players have reached an agreement that likely inches them further toward a future agreement on testing for human growth hormone, according to ESPN.
The NFL Players Association has informed players that they are conducting a population study to gauge the levels needed to determine a positive test for HGH.
Although no suspensions are going to be levied for HGH this year, according to ESPN, that is expected in the future once discipline is agreed upon with the league. A vote by the players is required for the proposal to become legal.
According to the report, the blood sample usage will be limited to the population study.
Players were told to be prepared to give a blood sample upon reporting to training camp.
The blood sample will only be used for the HGH population study, the memo states. Dr. Alan Rogol has been commissioned by the NFL and NFLPA to oversee the study.
NFL spokesman Greg Aiello stated that the ongoing talks with the players' union are set on resolving any remaining issues to get an HGH testing program started.
While this isn't an ultimate resolution yet, it's a strong step in that direction to try to make the sport cleaner and healthier because HGH has several long-term side effects that can cause diseases.
That includes heart issues, arthritis and diabetes.
