Dolphins head coach Joe Philbin told ESPN.com the running back job is "absolutely" still open, as the team has yet to settle on one of Daniel Thomas or Lamar Miller as the starter.
"I think they both had a productive camp, and there is still more to be played before we make a final decision," Philbin said.
Neither player has really stood out in the preseason in limited chances, though Miller is the only one of the two to have scored in the first three games. Miller has rushed for 37 yards on nine carries, while Thomas is at 49 yards and 12 carries.
When asked whether the starting position was just a symbolic position, Philbin did not agree with that assertion.
"We want to reward the guys we feel earned positions on the football team, so obviously it will be important who the starter is," he said.
