Cowboys DE Randy Gregory withdraws 10-game suspension appeal

Report: Cowboys' Randy Gregory withdraws appeal of his 10-game suspension for violating NFL's substance abuse policy.

Dallas Cowboys defensive end Randy Gregory withdrew the appeal of his 10-game suspension for violating the league's substance abuse policy and will now be suspended 14 games, reports ESPN's Adam Schefter and Todd Archer.

Cowboys owner Jerry Jones confirmed on 105.3 The Fan on Tuesday morning that Gregory's appeal had been dropped upon the NFLPA's decision that it wasn't worth pursuing.

Gregory will not be eligible to play again until Week 16 against the Detroit Lions on Dec. 26.

Gregory was placed on the reserve/did not report list at the beginning of training camp and was released from substance abuse treatment facility this month.

A second round pick in the 2015 NFL draft, Gregory has failed multiple drug tests since entering the league, including testing positive for marijuana at the NFL scouting combine.

Gregory played in 12 games as a rookie, recording 11 total tackles.
