I'm guessing here but I have to think that the steelers will cut Fernando this week, or shortly thereafter.
McFadden will hopefully be healthy this week, giving us a full complement of CBs and a backup or two. In case no one noticed, Fernando was inactive this past week against the pats, the team he practiced with this pre-season. That means that anthony madison was ahead of him on the depth chart - never a good sign.
They already made a roster move this week to put Paxson in for Dline getting rid of Najeh. Personally I'd like to see donovan woods back on the team to further bolster our ST. I'd be fine with fernando sticking around, but not if he is going to be inactive when we are missing a starter.
