NFL introduces game-day testingAdolpho Birch, the NFL‘s senior vice president of law and labor policy, recently said the league will drug test for steroids on game days.

NFL will use the game-day testing only for performance-enhancers and not for recreational drugs like cocaine and marijuana.

“This is primarily a competitive issue, so we do not contemplate utilizing it for the substances-of-abuse recreational drugs,” Birch said during a conference call. “But it is something that will involve any of the potential testing we do under the steroid policy.”
