The New York Times is reporting that the NFL is considering having the World Anti-Doping Agency oversee testing of players for performance-enhancing drugs if a federal appeals court forces the league to end the lockout and implement rules for operating the league this season.
The Times cited an unidentified NFL official briefed on its planning.
The newspaper reports bringing in WADA could eventually lead to players being blood tested for human growth hormone for the first time.
The NFL and players are locked in a labor battle that has gone to the courts. The owners are currently locking out the players, who have dissolved their union and sued the owners in federal court.
