February 1: The starting time has been pushed back a second time, to 9 pm ET, after the Spurs had travel issues, per the league (Twitter link). As Tom Orsborn of The San Antonio Express-News writes, the Spurs’ plane had a “minor equipment issue,” which forced the team to divert to Atlanta and board a new plane.
January 31: The starting time for Sunday’s game between the Magic and Spurs in San Antonio has been moved from 4 pm to 7 pm ET due to weather issues, the NBA announced (via Twitter).
The Spurs played Saturday afternoon in Charlotte in a game that was moved up three hours because of a major winter storm moving through North Carolina. They were expecting to return home after the game, but were stuck on their private plane for two hours before the airport was shut down.
The team spent the night in Charlotte with hopes of flying back to San Antonio in the morning. Further changes may have to be made if conditions haven’t improved by early Sunday.
The Magic arrived in San Antonio late Saturday afternoon, according to Jason Beede of The Orlando Sentinel (subscription required), and should have a significant rest advantage if the game is able to be played on Sunday.
Two games were postponed last Sunday because of Winter Storm Fern, and two others started early on Monday due to weather conditions. The postponed games — Denver at Memphis and Dallas at Milwaukee — were rescheduled for March, which caused the dates of two other games to be moved.

“Stuck on their private plane” oh lets all have a big cry for these guys…give me a break.
They were eating steak and playing cards, not suffocating in coach with those little air conditioner nozzles that just blow the farts at you more
This move is not a good idea, people already have plans for the game, and Adam Silver is always trying to help his favorite teams; this move is clearly in San Antonio’s favor.
