Bollywood superstar Shah Rukh Khan has pulled a muscle while shooting for his upcoming film ‘Fan’ in Croatia.

The 49-year-old actor, who is shooting the Maneesh Sharma-directed film, tweeted that he was in lot of pain.

“Serious ouch time! Hamstring shaken fortunately not stirred. Injections galore, running like a duck. Not that I don’t like ducks but it sucks!,” SRK tweeted.

In some photos obtained from social media, the ‘Happy New Year’ star is seen running around the streets of Croatia after being chased by a bike rider during a scene.

‘Fan’ is slated to release later this year.
