Eagles' Saquon Barkley says the NFL drug tested him after pulling off backward hurdle

Philadelphia Eagles running back Saquon Barkley did something so extraordinary on the football field that the NFL drug tested him right after the game. 

During the second quarter of the Eagles' 28-23 win over the Jacksonville Jaguars, Barkley caught a pass from quarterback Jalen Hurts, juked around one Jaguars' defender and spun away from another.

As Barkley was finishing his spin move and his back was turned toward a third Jaguars defender, he improbably hurdled over the defender while facing backward.
