Franklin, 68, had been scheduled to perform her first two shows in Brooklyn ever this month. One concert was to take place in Wingate Field in East Flatbush Monday and the other at Asser Levy Park in Brighton Beach Aug. 12, CNN said.
There were no details on how she suffered the injury and how many ribs were affected.
"Due to fractured ribs and pain in the abdomen, it was necessary for Ms. Franklin to cancel and reschedule the two concerts," said a statement from spokeswoman Gwendolyn Quinn issued to CNN.
"I was very much looking forward to being in Brooklyn and having a foot-long hot dog at Coney Island," Franklin added in the statement. "Hopefully, I will get it before the end of August."
