I cant envision Gronk being ready. He has a history of speeding up recovery which causes a reoccurring injury. With 't something this serious, I don't think Big Bill is going to but his Million Dollar Baby on the line vs. a rebuilding franchise.
Hernandez, on the other hand, can almost be slotted in as out. Whether it be incarceration or suspension, he won't be playing.
The real question this topic is missing:
What kind of impact will having only one, or very possibly none, of their star TE's have on the outcome of the game?
