MINNEAPOLIS ? When Derek Lee trudged out of practice Wednesday afternoon and climbed aboard a waiting bus, the junior center for the University of Wisconsin men?s hockey team took with him a somewhat cruel reality. Lee is still feeling the effects of a concussion suffered Jan. 28, which means he won?t play for UW Friday and Saturday nights when it faces Minnesota in a Western Collegiate Hockey Association series at Mariucci Arena. It also means the Badgers will go an entire regular season without having their full complement of players due to injury, illness or recuperation.
