It took most of Thursday morning to locate Hardy, according to Rapoport. The Cowboys listed an illness as Hardy's official reason for missing practice.
It's the latest eyebrow-raising incident involving Hardy, who recently returned from a four-game suspension stemming from a 2014 domestic violence incident that ended his Panthers career and landed him on the Exempt/Commissioner's Permission List for the final 15 games of the 2014 season.
In the fourth quarter of Sunday's loss to the Giants, Hardy entered the Cowboys' special teams huddle and slapped the clipboard of special teams coach Rich Bisaccia. Hardy also got into a verbal confrontation with wide receiver Dez Bryant. Cowboys coach Jason Garrett told reporters on Monday that Hardy would not be disciplined for his actions.
