Lamar Miller

Dolphins Knowshon Moreno returned to practice Monday and is working with a bulky protective brace on his elbow. The Dolphins are trying to figure out if he can play with the brace.

"I think it's just a matter of him getting used to playing with it in practice. He's got to get a feel of it and carrying the ball with it, pass protection," coach Joe Philbin said. "Obviously we just can't have him in there when we are running the ball or free release him all the time. Those are things we take the practice week to figure out."

When Moreno is cleared to play he'll likely compete with Daniel Thomas for the role as Miami's third-down back, which was the spot he held in the season opener.

The Dolphins' rushing attack has done just fine without Moreno, averaging 142.3 yards per game and 5.0 yards per carry. Miami enters this Sunday's game against the Green Bay Packers, who are allowing 163 rushing yards per game, fifth in the NFL in rushing. Lamar Miller did well against the Chiefs and Dolphins so the matchups were favorable, and many feel he's not lead back material. The story mentions Moreno will compete with Thomas for third down back duties, but there really shouldn't be much competition here assuming Moreno can perform. Moreno was arguably their lead back before he got hurt.
