Nikhil Dwivedi, who fractured his hand during the shoot of "Hate Story", has to undergo surgery to rectify his wrist bone, according to sources close to the actor.

"Nikhil was under the impression that the injury on his right hand has healed and so with all enthusiasm, he resumed shooting for 'Tamanchey'. But while doing a basic action sequence, his wrist bone snapped and the MRI revealed that wrist bone had actually never healed and the fibres had been further damaged," said a source.

Now he will have to undergo surgery to insert metal bolts for joining his wrist bone.

"Though he will finish off shooting this schedule with pain killers, he will undergo surgery and rest for two months post the operation with minimum mobility," the source added.

As of now, the source says, around 20 percent of "Tamanchey" still needs to be shot, and Nikhil is trying to complete it at the earliest.

Once he wraps up work, the surgery and recovery will be his first priority.
