The NFL Players Association "tentatively agreed" to let the league take 40 blood samples for HGH tests each week during the season, with a positive result drawing a four-game suspension, according to a memo the union sent players.
A copy of the NFLPA's email, written in a question-and-answer format, was obtained Tuesday by the Associated Press.
The memo says "a computer program will randomly select" five players apiece from eight teams each week for the tests.
First, though, every player in training camps this year will provide a blood sample and information about "height, weight, age, and race/ethnicity" for a "population study" to determine what level of HGH will result in penalties, the union wrote.
The NFLPA's letter says that if more than 5 percent of all training camp samples are above that threshold, players who fail will have "reasonable cause" testing the next two seasons — meaning they'll be subject to additional testing, and an eight-game ban if they're caught again.
No date has been set for the start of testing, because there are still issues that need to be negotiated between the NFL and union. League spokesman Brian McCarthy declined to comment on any specifics in the union memo, telling AP in an email: "We do not have yet a comprehensive agreement for HGH testing."

Perfect fete: The Miami team that had the only perfect season in NFL history will be honored by the White House on Tuesday, more than 40 years later.

The '72 Dolphins didn't make it to the White House in the months after their Super Bowl victory because President Nixon — a big sports fan — was immersed in the Watergate scandal.
