The Jets also sent 10 other players to their American Hockey League affiliate.
Coach Claude Noel says they have seen enough from the young players already in their system so they decided to let White go.
It leaves 37 players still in camp, including 2013 draft pick Josh Morrissey.
At just 18, Morrissey hasn't looked out of place among some of the more seasoned prospects in camp.
The Jets are playing Minnesota again Saturday after dropping a 4-1 decision to the Wild last Thursday night.
