CBS 58NEW YORK (AP) — The NBA has announced new dates for four games as a result of the winter storm's impact on the Memphis and Dallas areas. Poor weather last weekend forced the postponement of two scheduled Sunday games: Dallas at Milwaukee and Detroit at Memphis. The Nuggets-Grizzlies game has been rescheduled for March 18, while the Mavericks-Bucks game now will take place March 31. The dates have been changed for two other upcoming games to accommodate the weather-related schedule shifts. A Grizzlies home game with the New York Knicks will be April 1 instead of March 18.
