Dallas Cowboys defensive end Randy Gregory has again been suspended by the NFL, this time for a year.
Gregory, 24, will serve a one-year suspension without pay for violating the NFL Policy and Program for Substances of Abuse for a third time.
Gregory recently spent time in a rehab facility for previous violations of the substance abuse policy that earned him two suspensions totaling 14 games.
The suspension begins immediately and makes Gregory unavailable for the Cowboys this postseason. The Cowboys are the No. 1 seed in the NFC and will next play Jan. 15.
Without another violation, Gregory may be available for next postseason.
Gregory completed his latest suspension a couple of weeks ago and joined the team on the field for the first time during the week 16 win over the Detroit Lions.
The defensive end got off to a slow start with two tackles against the Lions, but in the regular season finale against the Eagles had six tackles and an assist on a sack.
Gregory slid to the Cowboys at the end of the second round in the 2015 draft after testing positive for marijuana at the NFL combine.
