Bullard cited the Richardson City, Texas, jail.
The substance he was arrested for was cocaine, according to TMZ, adding the charge was a felony.
Davison clarified that Hardy was arrested for possessing less than one gram of a controlled substance. Tom Pelissero of USA Today provided his mugshot:
Mike Leslie of ABC 8 in Dallas noted Hardy was arrested at a traffic stop at 12:18 a.m. CT in Richardson.
Hardy has run into trouble with the law in the past.
Although those charges were dropped, Michael David Smith of Pro Football Talk pointed out Hardy "was already a long shot to return to the NFL even if he stayed on his best behavior, and a drug arrest could end any hope he had of playing in the NFL again."
The Cowboys elected not to bring Hardy back after a turbulent 2015 campaign.
Ryan Wilson of CBS Sports chronicled the handful of issues the organization had with the defensive lineman: He got into a shouting match with wide receiver Dez Bryant on the sidelines, shoved an assistant coach, made ill-advised comments in light of his four-game suspension about how he would return to the field "guns blazing" and told Clarence E. Hill Jr. of the Star-Telegram he would hit New York Giants quarterback Eli Manning "in the mouth."
Hardy played for the Panthers from 2010 to 2014 before joining the Cowboys in 2015. He has amassed 40 sacks in 75 games in his career, reaching the 2013 Pro Bowl with 15 sacks.
