On Tuesday, the singer tore her right hamstring, one of the muscles at the back of the knee, while practicing in Los Angeles for an upcoming TV special.
"She overdid it," Yvette Noel-Schure, a Columbia Records spokeswoman, said Wednesday.
"We're all keeping our fingers crossed that, because she's young and healthy, it heals fast. There are a lot of things in place that we may have to shift. Not the album, which is finished, but side (appearances). We'll know more after a week," Noel-Schure said.
The performer was treated by a private sports-injury specialist, who advised her to undergo a short-term physical rehabilitation regimen.
She is able to walk, but was advised to steer clear of dancing and other strenuous physical activity for approximately one week.
The new album from the trio, which also includes Kelly Rowland and Michelle Williams, is titled "Destiny Fulfilled" and set for release Nov. 16.
