They only recently reunited, but already fate delivered Destiny's Child a slight setback when Beyoncé injured her leg during a dance rehearsal.

The singer tore her right hamstring while practicing dance moves in Los Angeles Tuesday for an upcoming TV special with fellow group members Kelly Rowland and Michelle Williams, according to The Associated Press. She was treated by a private sports-injury specialist who advised her to avoid dancing and other demanding physical activity for about a week.

A spokesperson for the group told the AP that some of the trio's plans would be delayed until Beyoncé's leg heals.

"She overdid it," Columbia Records spokesperson Yvette Noel-Shure said. "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."

One of the projects that could be postponed is the group's planned video shoot for its first single, "Lose My Breath," which went to radio earlier this month. Destiny's Child were slated to start shooting on October 8 in Los Angeles with director Marc Klasfeld, but whether or not that will continue as scheduled remains to be seen -- label rep Michelle Welch said that they're currently waiting to find out.

The group has completed its first album in three years, Destiny Fulfilled, which will hit stores on November 16.
