NFL Players to Be Tested to Determine Natural HGH Levels

Drug warriors complain that it's a delaying tactic to stop doping enforcement

NFL players will be required to provide blood samples during training camp physicals for a study on human growth hormone, according to emails the players' association sent to its members that were obtained by USA TODAY Sports.

The population study will be used to determine what a "normal" HGH level is for an NFL player as negotiations continue on several other issues, including discipline for those caught with increased HGH levels, before testing is implemented across the league.

"I don't think it's a big issue," said Kansas City Chiefs offensive lineman Geoff Schwartz. "The testing is just to establish baselines. We agreed to testing in the CBA and this is the first step in that process."
