Wednesday’s rivalry game between No. 8 Duke and North Carolina was postponed due to a storm that brought enough snow and ice to paralyze many area roads. The game will be played Feb. 20, though the time is still undetermined. The postponement came about 3 1/2 hours before the scheduled tipoff at 6:10 p.m. PST. UNC athletic director Bubba Cunningham said in a statement that Duke’s bus couldn’t make it to the Durham campus to pick up the Blue Devils for the 11-mile drive to Chapel Hill. He called the postponement “the best decision to make at this time” due to safety.
