The NFL issued a response to Eric Reid's declaration that he's been drug tested five times since signing with the Carolina Panthers.
NFL spokesman Brian McCarthy provided some information about the league's random drug testing policy on Twitter.
"Each week during the season, 10 players per club will be tested," McCarthy wrote. "By means of a computer program, the policy's jointly appointed Independent Administrator randomly selects before the game players to be tested."
The league's response comes after Reid commented on being randomly selected for a drug test after the Panthers' 52-21 loss to the Pittsburgh Steelers on Thursday.
