Longtime men’s basketball rivals North Dakota and North Dakota State have extended — and expanded — their series.

UND officials announced Thursday that the two teams will play each other twice each season for the next four years. The teams have been meeting once a year since 2010.

This season’s schedule calls for the Fighting Hawks and Bison to play December 7th at the Scheels Center in Fargo and December 16th at the Betty Engelstad Sioux Center in Grand Forks.

UND head coach Brian Jones says a home-and-home series makes sense because the schools are 70 miles apart and it gives each team a high-level opponent.

The Fighting Hawks own a 159-132 advantage in the series, which began in 1904. NDSU has won four of the last six games.
