In a social media post, Bruce says his medical advisors urged him to take it easy and postpone the shows.
Bruce and the E Street Band were supposed to perform Thursday in Syracuse, NY ... but that show is on hold, ditto for upcoming gigs this month in Maryland, Pennsylvania, Connecticut, Ohio, New York and Washington D.C.
In a statement, Bruce says ... "Over here on E Street, we're heartbroken to have to postpone these shows. First, apologies to our fabulous Philly fans who we missed a few weeks ago. We’ll be back to pick these shows up and then some. Thank you for your understanding and support."
