Aamir Khan suffered a muscle spasm on one of his shoulders when he was shooting for his film "Dangal". However, the actor took to Twitter to say that it is not a major injury.

"Hey guys, it's not such a major injury. My back muscle has gone into a spasm. A week of rest and I will be back on shoot," Aamir tweeted.

Aamir suffered the injury on Saturday night when he was shooting for a fight scene in "Dangal". Following the injury, the actor returned to Mumbai, as he has been advised bed rest.

"Following the injury, Aamir took 24 hours of rest in Ludhiana as he could hardly move. Now, he has been asked to take complete rest for eight days after which doctors will decide the next course of action," Aamir's spokesperson told IANS.

The cast of "Dangal", including Sakshi Tanwar, Fatima Sana Shaikh and Rajkummar Rao are on a break until the superstar is able to work again.

Aamir's wife Kiran Rao and son Azad were with the actor when the injury struck.

Directed by Nitesh Tiwari, "Dangal" is based on a real life story of wrestler Mahavir Phogat. The film is set for 2016 Christmas release.
