NFL training camps currently are set to open on July 28, in 19 days. The NFL Players Association has reminded players that, when they show up, they are subject to unannounced drug testing.

The new labor deal moved the opening of the window for annual substance-abuse testing from April 20 (yes, 4/20) to the launch of camp.

“You must be prepared to drug test as soon as camp opens,” the NFLPA said in an email to all players.
