Randy Gregory won’t be seen on the field for quite some time.

The NFL announced on Thursday that Cowboys’ defensive end was suspended for violating the league’s Policy of Substances and Abuse. This will be the third time this year the former Nebraska star has been suspended.

Gregory has served four-game and 10-game suspensions this season for violating the substance abuse policy. His suspension begins immediately and it has been reported that he can apply for reinstatement on Nov. 6.

He will miss all of Dallas’ playoff games this season.

Gregory was selected as the 60th overall pick by Dallas in the 2015 NFL Draft. He started in 20 games at Nebraska in 2013 and 2014, totaling 120 tackles, 29 tackles for loss and 17.5 sacks for his career. The defensive end was also a first-team All-B1G selection and third-team All-American after the 2014 campaign.

With his suspensions this season, Gregory only saw action in two games and tallied eight stops and a sack.
