Congress examines science behind HGH test for NFL
A congressional committee has opened a hearing to examine the science behind a human growth hormone test the NFL wants to start using on its players.
Nearly two full seasons have passed since the league and the players' union signed a labor deal that set the stage for HGH testing.
The NFL Players Association won't concede the validity of a test that's used by Olympic sports and Major League Baseball, and the sides haven't been able to agree on a scientist to help resolve that impasse.
Among the witnesses before the House Oversight and Government Reform Committee on Wednesday is Pro Football Hall of Fame member Dick Butkus. In his prepared statement, Butkus writes: "Now, let's get on with it. The HGH testing process is proven to be reliable."
