Miller missed Thursday's practice with a hamstring injury, Nick Underhill of NewOrleans.Football reports.
Coach Dennis Allen declined to say if the injury is a threat to the rookie's Week 1 availability, which takes on greater importance with Alvin Kamara suspended for the first three games of the season. Jamaal Williams is expected to start, with RB/WR Kirk Merritt and practice-squad addition Tony Jones being the other options besides Miller for backfield depth.
