The injury is not expected to keep him out of action for an extended period of time.
The third-year running back was injured in the first half of Monday's 17-10 loss to St. Louis in the Hall of Fame Game. He left the game and did not return.
The news also was good as far as defensive end Jason Taylor and quarterback Ray Lucas were concerned.
Both players underwent MRIs, and both exams revealed no damage.
Taylor sustained a "stinger" in his left shoulder in the first half. He is expected at practice when the Dolphins get back to the field on Wednesday.
The same goes for Lucas, who suffered back spasms while sitting on the bench between series in the first half.
