NEW YORK — Justin Bieber is down for the count.

The 16-year-old singer is too sick to perform Sunday at the New York State Fair, organizers announced on the fair's website.

Luckily, fans will still get to see Bieber. He has rescheduled the performance for Wednesday at 7 p.m. As a result, he had to shift his planned Wednesday date in Manchester, N.H to Dec. 9.

"I'm getting rest right now and trying to recover from the not so good news from the doctor," Bieber wrote Sunday on Twitter. "I'm gonna be ok just need 2 rest but i wanted all of u 2 know i never want to let any of u down. ever. i really appreciate all the kind words."
