Actress Sonakshi Sinha's sprained foot has come in the way of promotions of her forthcoming film `R... Rajkumar`.

`R... Rajkumar`, which also stars Shahid Kapoor, is set for Friday release and Sonakshi regrets not being able to travel for the last lap of promotions.

`Sorry Hyderabad and Bengaluru - couldn't make it today! 'R...Rajkumar' ka power man, sprained my foot! That too only after interval! Three days to go,` she posted on Twitter Tuesday.

She was recently seen limping around while promoting the film on one of the reality shows.
