Narang, who clinched a bronze in the 10m air rifle event, confirmed his attendance last night.
"Sports Minister Ajay Maken was our first choice to flag off the race but we were not aware of today's cabinet reshuffle," said an official of the Jaypee Group, the organisers of the event.
Earlier, there was speculation that actor Hrithik Roshan had been finalised to flag off the race at the Buddh International Circuit here.
