Performance enhancing drug testing just got more complicated for the NFL.
On Tuesday, the league warned its players that eating meat while traveling in China or Mexico could result in a positive test under its substance abuse policy.
The meat in these countries could contain clenbuterol, a muscle-building and weight-loss stimulant that is banned by the NFL. The independent administrator of the league’s drug testing program sent a memo to players warning them about consuming meat while overseas.
“Players are responsible for what they put in their bodies,” the memo said.
On Nov. 21, the Oakland Raiders and Houston Texans will square off in Mexico City in a game that is part of the NFL’s international series. Understanding the risk of consuming clenbuterol in meat, the players might consider going vegetarian for a day or two.
