Foles injury sounds like a cracked rib, at least a bruised rib. I don't know if he will take a cortisone shot to alleviate the pain (or other pain suppressor), but it's going to be really tough for him to practice this week and to throw naturally. Wentz will certainly be clamoring to play, and he's at least capable of practicing. Sudfeld is untested and has not practiced much this year, although the Eagles are continually reported to be "high" on him. Very interesting sub-plot to follow this week.
And, replying to Lawman, I'd like to see Howie find a way to keep both QBs. Foles is certainly capable of magic, and Wentz of playing at MVP-level.
