Randy Gregory’s draft stock likely took a hit Wednesday when the defensive end/outside linebacker admitted he failed a drug test at the NFL Combine.

Gregory admitted as much in an interview with the NFL Network.

“I blame myself,” Gregory told Kim Jones of the NFL Network. “And I know it sounds cliché, but there’s really no one else I can blame.”

As a result of the failed test, Gregory will enter the NFL’s drug system and will be tested more often than other players for recreational drugs.
