The Miami Dolphins received some good news when starting running back Lamar Miller returned to practice on Tuesday. Miller received a concussion in the third quarter of Sunday’s victory over the Pittsburgh Steelers. Miller’s status for this week against the New England Patriots remains up in the air. However, Miller was at least limited in the portion of Tuesday’s practice open to the media. Miller must pass all the concussion tests this week in order to return to the field Sunday against New England.
