John Abraham's high octane action sequences in 'Force 2' had caused him a severe knee injury. While shooting in Budapest for the second installment of the action drama, he was supposed to kick open a door, however this action sequence ended up wounding John's knee.
Blood clots were immediately treated by doctors. He was advised a three day bed rest but he resumed shooting. And this worsened the situation more and the actor has to undergo a surgery.
John shared a picture of him and wrote, "Thank you for all the well wishes! Getting better every day and will be back to the set soon hopefully! Thank you to the amazing doctors (Maniar) and nurses!"
So meanwhile they will complete all the dialogue shots and once he is fit they shall finish the action sequences. 80% of the film is complete and crew shall return to India in mid-October 2015.
