Justin Bieber has re-scheduled his Sunday Aug. 29 concert at the New York State Fair to 7 p.m. Wednesday Sept. 1.

The concert was postponed due to the 16-year-old pop star’s illness, according to Fair and Bieber representatives.

An additional 200 tickets were made available to the previously sold-out show this morning at the Fair box office. The Fair will honor all tickets issued for Sunday’s show for the new date on Wednesday Sept. 1. Any ticket that cannot be used should be returned to the point of sale for a refund prior to Wednesday’s show. The refunds will be processed beginning at 10 a.m. this morning.

Lady Antebellum is also scheduled to play the Fair Wednesday Sept. 1, at 8 p.m. at Chevy Court.
