Knowshon Moreno

Knowshon Moreno's elbow injury, which is expected to sideline him for several weeks, has opened the door for Lamar Miller to get more carries.

Miller is averaging a career-best 4.8 yards per carry this season in two games. The Dolphins (1-1) hope that continues when they host the Kansas City Chiefs (0-2) Sunday at Sun Life Stadium.

"I'm looking forward to it," Miller said. "Every running back wants the ball in their hands. So I feel like the more carries you get, the more comfortable you get with the team you're going against. I'm pretty up for the challenge."

Miller injured his ankle in Week 2, but it doesn’t sound like that is going to keep him out this week. The Chiefs are yielding 4.4 YPC through two games.
