The Raiders fear Bryant may be the subject of NFL discipline and are awaiting final word on the situation, which they believe to involve the league's substance-abuse policy, Michael Gehlken of the Las Vegas Review-Journal reports.
It's a somewhat vague notion -- but not surprising, considering Bryant's tumultuous history, which included a disappointing 2017 campaign with the Steelers after missing the 2016 season for violating the league's substance-abuse policy. If Bryant, who missed Thursday's final minicamp workout, breaches those rules again (even if it's not necessarily a failed test), he could face a suspension of one year or longer. Those wanting to use a late-round pick on Bryant this upcoming season will have to wait out yet another period of limbo.
