AceShowbiz - Fans were left disappointed when Madonna announced that her Monday, October 7 show at BAM Howard Gilman Opera in New York City had been postponed due to a previously undisclosed knee injury. In a statement shared on her website hours prior to the show, her team stated that the Queen of Pop is currently recovering.

"Madonna is currently dealing with a knee injury and has been advised rest for the next three days to assist in her recovery," so the statement read, telling concertgoers to "hold onto their tickets pending information on rescheduling." It continued to read, "We regret the inconvenience to fans. Thank you for understanding."

Madonna also took to social media to express her regret, along with a photo from the show. Mentioning her alter ego, she said, "It's Hard for Madame X to admit that she is also a human being made of flesh and blood and she must rest for the next 3 days to insure full recovery for her knee. I am not a quitter. This hurts me more than you can imagine. It's time to take those heels and fishnets off for a few days! Thank you for understanding. See you very soon!!"

While her Monday show had to be postponed, her concerts on October 10 and 12 are expected to proceed as scheduled.

The postponed show is a part of her Madame X tour, which kicked off earlier this month after a delayed start of nearly a month. Following her shows at BAM Howard Gilman Opera, the "Like a Virgin" singer is expected to be heading to Chicago and San Francisco. The opening night of her Chicago show, which was originally set for October 5, was pushed back due to unknown reason. Meanwhile, her first San Francisco concert was moved to November 5 due to production issues.

The North American leg is expected to conclude on December 22 in Miami, Florida.
