From the Footballguys News Blogger:
National Football League Players Association executive director Gene Upshaw said on Saturday that his organization does not currently support the idea of taking samples of players blood in order to test for the growth hormone HGH. "When you start talking about coming in to take a person's blood, that's different than taking someone's urine," Upshaw said. "I know personally I would have a problem with someone coming in and trying to take the players' blood. I'm not ready to make that leap."
