Two NFL players have received bans for breaching the league's policy on doping.
Jermaine Cunningham from the New England Patriots and Eric Wright of the Tampa Bay Buccaneers will both be suspended for their next four games.
Wright tested positive for Adderall, a drug used to treat attention deficit disorder.
More than 20 NFL players have failed drugs tests since the 2012 season began.
Two Seattle Seahawks players are also facing bans for taking Adderall.
