The N.F.L.’s new drug-testing program includes provisions under which all players will be tested for human growth hormone at least once a year, and possibly many more times, the league said Saturday.
Tests for growth hormone require a blood sample, and the N.F.L. will be the first major American sports league to carry out blood testing at the major league level. League officials also said Saturday that this season, for the first time, drug tests would be conducted on game days.
Under the drug policy, there is no limit to how often players can be tested for steroids and H.G.H. during the season, and they can be tested up to six times in the off-season, said the league spokesman Greg Aiello.
