The Associated Press MEMPHIS, Tenn. — The NBA postponed two games on Sunday in Memphis and Milwaukee because of the massive winter storm that has made for dangerous travel conditions across much of the U.S. The Dallas Mavericks tried twice to fly to Milwaukee for their game against the Buc ks on Sunday night, but conditions didn’t allow it. A decision to postpone was announced a few hours before tipoff. Earlier Sunday, a game between the Denver Nuggets and Memphis Grizzlies was postponed about three hours before tipoff. Reschedule dates were not announced. The league also changed the start times for two games on Monday: Philadelphia 76ers at Charlotte Hornets will tip off at 3 p.m. ET instead of 7 p.m., and the Indiana Pacers at Atlanta Hawks at 1:30 p.m. instead of 7:30 p.m. The Memphis area was experiencing a mixture of snow, sleet and freezing rain that began falling early Saturday morning and continued Sunday morning. South and east of Memphis, freezing rain has collected on power lines and trees, causing widespread outages and blocked roads. Authorities had recommended people stay off the streets as the wintry mix and frigid temperatures caused a refreeze. The Nuggets planned to fly out at some point on Sunday, depending on the conditions at Memphis International Airport. They are scheduled to play at home Tuesday against the Detroit Pistons. The Grizzlies are scheduled to play the Rockets in Houston on Monday. ...read more read less
