On Saturday night, 17 people at anEd Sheeranconcert were taken to the hospital for heat-related illnesses.

At the latest stop on his+ - = ÷ x (“Mathematics”) Tour, the singer-songwriter, 31, played Acrisure Stadium in Pittsburgh, where temperatures climbed to a high of 87 degrees on Saturday, according to data fromThe Weather Channel.

Published on Sunday, the release states that EMS personnel on-call during the concert received “37 calls for service, with 17 transports to the hospital.”

All of the transports were for “heat-related issues” including “some falls, one seizure, and two cardiac arrest patients,” Cara Cruz, an information officer for the city, wrote in the statement.

The cardiac arrest patients were not audience members, but rather a “worker tearing down the setup inside the stadium went into cardiac arrest on the floor,” and a paramedic from an outside agency who went into cardiac arrest while exiting the stadium.

Sheeran has not said anything publicly about the heat, and a representative for the musician did not immediately respond to PEOPLE’s request for comment.

The “Shape of You” singer did, however, dedicate an Instagram post to audience members of the Pittsburgh show.
