Here is the official announcement from TNA about postponing their tour of India:
Multi Screen Media (MSM) and TNA Wrestling, the international professional wrestling entertainment organization, jointly announced today that the TNA One Night Only: Mumbai live event has been postponed.
The live event that was scheduled to take place on December 4, has now been postponed to 2016 to a yet-to-be decided date. The postponement is primarily due to logistical issues around the timing of the event.
As soon as the new dates are firmed up, it will be announced in an update.
While TNA is looking forward to coming to India soon, MSM is geared up to host the entire entourage of TNA in India.
