Sonia was demonstrating a step to Siddharth using a wheelchair, and she accidentally ended up hurting her foot earlier this week.
"She had to get a few stitches after the incident," a source from the set of the Colors' show told IANS.
However, the injury did not deter Sonia from choreographing the entire act. She kept her spirits high, and got Siddharth, who plays Shiv in "Balika Vadhu", to do the steps right on the groovy number "Party on my mind" from "Race 2".
Their performance will be seen on the episode, which will be aired Saturday.
