A Hunter Hayes concert scheduled for Nov. 20 at Chaifetz Arena in St. Louis, Mo., has been canceled.

"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," reads a statement on the arena's website. "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."

Gov. Nixon declared a state of emergency throughout the state on Monday (Nov. 17). It's a precautionary measure ahead of the announcement of a verdict in the trial of Ferguson, Mo., police office Darren Wilson, who is accused of killing unarmed teenager Michael Brown, an African-American, on Aug. 9.

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

The timing of the verdict announcement is unknown, but CNN reports that prosecutors have said the grand jury may be done deliberating in mid- to late November.

Hayes' Tattoo (Your Name) Tour is set to continue Nov. 21 in Chicago, Ill. Dan + Shay and the Railers are joining him at all dates.
