Singer posts on his Twitter feed it is due to health reasons

The first of Justin Timberlake’s two concerts at Madison Square Garden has been postponed.
The singer posted on his Twitter feed on Wednesday that the postponement is due to health reasons. The show originally scheduled for Wednesday has been rescheduled for Friday.
Timberlake apologised on Twitter and said: “It kills me to have to do this. I hope to see you all on Friday.”
On its website, MSG says ticket holders can get a refund if they want, starting on Thursday morning.
