To me the pertinent info in that article are:
1) neither Fargas nor McFadden practiced Wednesday. That doesn't mean they won't play, but generaly it isn't a good sign.
2) McFadden is in a boot. Again, not a good sign. Doesn't mean the boot won't come off Sunday, but usually boots are not good.
3) Kiffin's comment was not encouraging: “It doesn’t look very good right now,” coach Lane Kiffin said. “The sooner he can get back, the better for us. He’s very valuable to us, especially in protections, so, hopefully, we’ll have him back. But it doesn’t look very good.” Doesn't look very good---repeated twice. THAT doesn't look very good.
4) As for Fargas: the writer doesn't quote anyone but he claims that the Raiders are not optimistic and also says that Fargas' injury is worse than DMacs: "The injury to Fargas is more serious and the Raiders are not optimistic about his chances to play against the Bills.
This one will bear watching but if these guys are still sitting on the sidelines on Friday, it is time to jump on the Bush bandwagon. No matter what happens, when healthy, Dmac is going to get at least 50% of the reps; but I think the door is open for Bush to show what he can do and move ahead of Fargas in the team's long term plans and maybe carve out a time share for himself with DMac.
