Randy Gregory withdrew the appeal of his 10-game suspension for multiple violations of the NFL's substance abuse policy and now will be suspended 14 games in full, through Week 14.
Gregory won't be eligible to play this season until Week 15.
He spent time in rehab and was released earlier this month. He has not been around the team since the offseason.
At the 2015 NFL scouting combine, Gregory tested positive for marijuana, which put him in the league's drug program.
