Michigan State has eliminated the blue lines at Munn Ice Arena.
At the request of athletic director Mark Hollis, the blue lines were painted green when the ice recently was redone at the hockey rink.
Hollis did not respond to repeated requests from the Free Press for comment.
Section 5 a. of the NCAA Ice Hockey Rules and Interpretations states that “the ice area between the two goals shall be divided into three parts by lines 12 inches in width and blue in color, drawn at least 60 feet out from the goal lines, extending completely across the rink parallel with the goal lines, and continuing vertically up the side of the boards.
