Dallas Cowboys DE Randy Gregory returns from suspension.

FRISCO, Texas — Dallas Cowboys defensive end Randy Gregory, who was suspended all of last season over multiple violations of the NFL’s substance-abuse policy, was reinstated Tuesday.

Gregory can join the Cowboys at training camp in California next week and will be eligible for games as long as he continues to meet the terms of his reinstatement, the league said. The team reports to Oxnard on July 24, two days before its first practice.

The NFL said Gregory was immediately eligible for meetings, conditioning work and “similar activities” and would be cleared for practices and games once “arrangements have been confirmed regarding Gregory’s clinical resources in Dallas.”

Gregory, 25, last played in the 2016 regular-season finale, when the former Nebraska standout had his first career sack at the end of his second season. He was suspended before Dallas’ playoff loss to Green Bay, his third suspension of the season.

Gregory slid to the Cowboys at the end of the second round in 2015 because of off-field concerns that included a positive test for marijuana at the NFL Combine.

The Cowboys have backed Gregory’s attempt to return to the field, with several teammates writing letters of recommendation to the NFL as part of the process of him applying for reinstatement.
