“The Shakira and Jason Aldean and Brooks & Dunn performances originally scheduled for May 29th and May 30th respectively at Fenway Park have been canceled,” reads a statement in English and Spanish. “Refunds will be available at your point of purchase. We apologize for the inconvenience.”

In statement shared with Billboard, Live Nation said: “During a routine pre-show check, structural elements were identified as not being up to standard, so the shows were canceled. All team members are safe.”

Billboard reached out to Shakira’s team for additional comment.

Shakira had previously announced that will.i.am and Wyclef Jean were set to perform with her onstage in Boston, joining a growing roster of guest artists she’s had throughout her world tour.

The show in Boston was set to be part of Shakira’s Las Mujeres Ya No Lloran World Tour, currently underway in North America. She had most recently headlined Sueños Festival in Chicago and is set to perform next in Washington, D.C., Atlanta, Miami, Los Angeles and Las Vegas, among other U.S. cities.

Shakira was No. 1 on Billboard’s Top Tours chart for March. She also led February’s list with $32.9 million, but doubles her earnings on the newest update. According to figures reported to Billboard Boxscore, Las Mujeres Ya No Lloran World Tour earned $70.6 million from 11 reported shows — more than any act has grossed in any March since the charts launched in 2019.
