Apparently Crabtree was found to have a stress fracture in his foot that he is going to get surgery on. A relatively minor injury and minor surgery. It will put him out 6-10 weeks. That means he may not be able to run the 40 or do shuttle and passing drills until right before the draft.
This could drop his draft value. That means that the very slim chance of someone trading with us to get in front of Seattle to grab him just became miniscule.
