New England Patriots tight end Rob Gronkowski will start the preseason on the Physically Unable to Perform list, according to a person informed of the decision. That means Gronkowski will not be on the field with his teammates when they begin training camp. Putting Gronk on the PUP list was an expected decision, given that he had back surgery Tuesday -- his fifth surgical procedure this year. The source clarified on Wednesday that the move is for certain. Source: NFL.com
