Former players will receive human growth hormone as the NFL and its players union try to determine the impact of use on players' HGH levels, USA Today reported Wednesday.
The tentative plan is for about 100 to participate in the study, two-thirds receiving HGH and the others a placebo. Their HGH levels will be measured before and after. It's part of a study that will include blood draws from all current players to determine the highest HGH level a player can have without facing discipline under the league's new performance-enhancing drug policy, which is still being finalized.
HGH is naturally produced by the body, stimulating cell reproduction and regeneration. It also can be administered artificially and is banned by most international sports organizations as a performance-enhancing drug. It was unclear which former players agreed to participate or when the study would begin.
The NFL and union agreed to HGH testing in the labor deal finalized two years ago.
Denver star arrested: Broncos star linebacker Von Miller, who faces a four-game suspension for violating the NFL's substance-abuse policy, was arrested Sunday for failing to show up in court on traffic violations, the Arapahoe County (Colo.)

Miller was supposed to appear Dec. 31 on charges of careless driving, driving without a license and no proof of insurance for an incident Oct. 25.
Bengals: Receiver A.J. Green practiced for the first time since bruising his left knee during the first day of camp. He was not expected to play Saturday against the Titans.
Bills: Kevin Kolb will start at quarterback Friday against the Vikings. Coach Doug Marrone said his decision was not a reflection of EJ Manuel, a former Seminole who was 16-of-21 for 107 yards and a touchdown Sunday against the Colts. Kolb sat Sunday with a left knee injury.
