Karrion Kross has relinquished the WWE NXT title due to injury, he announced Wednesday night. He sustained a shoulder separation last Saturday at NXT TakeOver, in the main event match with Keith Lee -- the bout in which he won the title in the first place. Next Tuesday, NXT will hold a four-way, 60-minute Iron Man match for the vacant belt. Johnny Gargano, Tommaso Ciampa, Finn Balor and Adam Cole will be the participants.
