Updated: Country star Hunter Hayes' concert Thursday night at Chaifetz Arena has been called off.

A statement from the venue reads: "Out of respect for Missouri Gov. Jay Nixon's declaration declaring a state of emergency in Missouri, Hunter Hayes’ Thursday, November 20 show at Chaifetz Arena in St. Louis has been cancelled. Tickets will be reimbursed at the point of purchase. At this time, all other University related events at Saint Louis University this week are planned to go on as scheduled.

Hayes assures his fans that he will be back to St. Louis in 2015."

A Chaifetz spokeswoman could only refer to the official statement when asked about ticket sales.

A check on Ticketmaster for Saturday's show in Auburn Hills, Mich., showed that tickets were still available in the general admission pit down front as of Thursday afternoon.
