The incident occurred at the Chandivali Studios where Ranveer was shooting for a song. Apparently, Ranveer was performing his steps on an elevated structure, when he lost his balance and fell down, hurting his back and suffering injuries on his face.
Confirming the accident, Ranveer's spokesperson says, "Ranveer who has just completed the first schedule of Gunday, injured himself slightly while shooting the song sequence whereby his cheek has a small gash and required a few stitches. However, Ranveer is perfectly fine and is continuing with the shoot schedules as per plan."
Though the injury may not be too serious, Ranveer jokingly said "Now I am even more in character for Gunday."
