The NFL and NFLPA on Wednesday finalized plans for a human growth hormone study, which is seen as one step closer to implementing HGH testing among players.
The two sides agreed to a "population study" on Monday and the NFLPA informed its player reps and agents that all players will be giving a blood sample during preseason physicals, CBSSports.com reported. These samples should help medical experts determine acceptable and naturally-occurring levels of HGH in players.
The study is expected to lead to formulating a full policy for testing. The blood samples taken this preseason will be only for the purposes of the HGH population study and will not be tested for anything else, according to an email to the NFLPA membership
The NFL and NFLPA agreed to HGH testing two years ago as part of the 2011 collective bargaining agreement. But players have questioned how the testing would be conducted and who would oversee the testing.
Monday's email answers some of those questions.
ESPN said despite the population study, "no NFL players are expected to be suspended for HGH use this season."
