Richard Marshall has been dealing with a back ailment for a couple of weeks now. His play, frankly, has shown signs of those problems because it has not been training camp good.
Marshall was limited in practice Wednesday and today he's not practicing at all. He wasn't even on the field. Nolan Carroll is taking his place as the next guy up.
The troubling thing about that? Carroll was also limited in practice Wednesday with an Achilles' issue. So he's not at 100 percent, either.
That's not good news.
Reggie Bush is making some progress in that he did a few individual drills early in the open part of today's media session but his participation today is limited. The Dolphins are reporting him as practicing on a limited basis. He's still not 100 percent nor is he participating like he is.
And here is a harsh truth:
Because the Dolphins have tons more depth running back than they do at cornerback, because the Cardinals can threaten Miami so much with Larry Fitzgerald, who is last week's NFC Offensive Player of the Week, the absence of Marshall would be much more painful for the Dolphins to overcome than Bush.
