Samuel (hamstring) wasn't spotted during the media-access portion of Thursday's practice, Nick Wagoner of ESPN.com reports.
It appears as if Samuel will go down as a non-participant for a second straight session to begin Week 8 prep, giving him just one more chance to mix into drills Friday. And if he's unable to log a full practice, he seems destined to be tagged with a game-day designation for Sunday's road matchup with the Rams.
