Longer suspension?

FRISCO, Texas — Dallas defensive end Randy Gregory is facing a longer suspension over another violation of the NFL’s substance-abuse policy, and owner Jerry Jones said he doesn’t expect to see the troubled player at training camp in California.

With Gregory already suspended for the first four games this season, Jones said Wednesday that the Cowboys haven’t heard from the league about a possible 10-game ban for another failed drug test. A day after reports that Gregory was in rehab, Jones acknowledged that he was undergoing treatment.

Considered one of the best pass rushers in the 2015 draft, Gregory slid to the Cowboys at the end of the second round after he tested positive for marijuana at the NFL combine. His first suspension was announced in February.
