WWE NXT is expected to move to Tuesday nights following WrestleMania 37. As of now, the date for the move is set for April 13. The reason for it is due to Wednesday night NHL games airing on the USA Network.
However, things are on hold as negotiations between the NHL and NBC Universal have stalled. The Walt Disney Company, owner of ESPN and ABC, announced a seven-year rights deal with the NHL for roughly $400 million a year.
Pwinsider reported on Monday the current production calendar lists WWE NXT to be held and air on Tuesday, April 13. So all signs point to the move happening.
