The Providence Journal's Mark Daniels reports that wide receiver Malcolm Mitchell had a procedure done on his knee. He followed up by saying it would be an "uphill climb" for him to play in 2018.
UPDATE: Ian Rapoport reported that Mitchell's procedure was not a surgery, but rather to "promote healing" in his troubling knee. This is still not great for his 2018 prospects, but a clarification on what happened was necessary.
Mitchell's health has been a constant problem since entering the league, and it explains why rumors of the Patriots attempting to trade him leaked earlier today. Mitchell being out of the picture clears the way for players like Jordan Matthews and Kenny Britt to seize starting roles during Julian Edelman's suspension to start the year.
