Monday's decision follows last week's meeting with NCAA President Mark Emmert. North Dakota Gov. Jack Dalrymple and legislative leaders weren't able to persuade Emmert to let UND keep the nickname without any penalty.
A state law says UND has to keep the nickname. The Legislature is expected to repeal the law during a special session this November.
The higher education board voted unanimously Monday to retire the nickname by Dec. 31. UND had wanted to retire the nickname before Monday, but the approval of the state law blocked those plans.
