Rihanna has postponed several dates on her ANTI world tour, originally slated to begin on Feb. 26 in San Diego. The trek is now scheduled to kick off on Mar. 4, although performances scheduled after that date have also seemingly been reshuffled.

According to Ticketmaster, the first three performances of the announced ANTI tour have been postponed, with the San Diego date now coming on May 9. Several dates have been postponed in the second week of March as well.

Following the Feb. 28 show in San Jose moving to May 8, the San Jose Mercury News reports that “production delays” are the reason for the postponement. A rep for Rihanna did not immediately respond to Fuse’s request for comment.

Rihanna is set to perform at the BRIT Awards in London next week. She cancelled her GRAMMY Awards performance earlier this week due to illness.
