Morris (hamstring) didn't practice Sunday due to a hamstring injury, Alaina Getzenberg of ESPN.com reports.
Morris made the team's 53-man roster as the backup behind Dawson Knox and Tommy Sweeney, but he's picked up a hamstring issue that may sideline him for the season opener. The UDFA out of Bowling Green was elevated to the active roster for one game last year but is still looking to make his NFL debut.
