Elliott (hamstring) is doubtful for Saturday's preseason opener against the Rams, The Ft. Worth Star-Telegram reports.
He hasn't practiced in about a week, and the Cowboys don't want to take any chances with the fourth overall pick in this year's draft, so Elliott seems set to miss his first opportunity for game action in a Dallas uniform. Alfred Morris will likely start Saturday in his place, but expect sixth-round pick Darius Jackson to see significant snaps as well.
