Sources informed TOI, "Saif hurt his arm during the action scene and the unit had to stop shooting because of that twice as his arm started hurting badly. It was a scene which involved shooting at others, who are following him, while riding a jeep. Saif was hanging on the door and shooting while the jeep was going on high speed. Basically he had to hang on the road of the moving jeep. Suddenly the jeep's speed shot up over 80 km per hour, Saif's arm got pulled badly and he tore a muscle. It was actually a mistake of the stunt guy who got a bit nervous and drove too fast but Saif, instead of losing his cool, was very sweet to him and just told him to be more careful next time."
But a smart Saif did not make a mess out of it and continued to shoot till the end despite he had wounded his right arm severely.
