Raghu, known for being a tough taskmaster on the show, sprained his neck while trying his hand at a task called Water-Hangman. His injured neck left him reeling in excruciating pain and he couldn't move his neck for the next three days, says a source.
Raghu tries out a stunt before finalizing it for the contestants.
A few weeks ago, he got burns on his back while attempting a stunt involving fire. Following the incident, he had modified the task.
The show is currently in its eighth season and its tagline is "Shortcut To Hell".
