Juelz Santana was forced to pull out of a Michigan concert on Saturday (03Apr10) after undergoing a painful root canal operation.
The hip-hop star was scheduled to perform at Club 131 in Grand Rapids, but scrapped the show at the last minute after having the dental procedure.
Fans who arrived at the venue were told they will be able to redeem their tickets for a rescheduled show, according to AllHipHop.com.
The rapper issued an apology to fans on his Twitter.com page on Saturday night, promising to come back to Michigan soon.
He wrote: "I'm not gonna make it 2nite (tonight). Had 2 (to) get a root canal. Respect 2 promoter RIO. Makeup date is coming. Keep da (the) peace."
