Recently the NCAA announced that they were changing some rules to allow hockey players the right to return to junior hockey and stay enrolled in college.
Current student-athletes whose institutions will not be playing hockey during the fall semester will be permitted to participate in non-collegiate, amateur competition i.e. junior hockey on an outside team during the fall 2020 term (subject to school and conference approval). These student-athletes may compete on an outside team while remaining enrolled in their NCAA institution, which typically would not be allowed.
When they say junior hockey, they mean the USHL or CJHL not Canadian Hockey League teams (WHL, OHL, QMJHL), which are considered to be professional hockey by the NCAA.
