Sunil visited the show's set earlier this week along with a family of lookalikes of Bollywood actors.
Everything was going well until when Sunil had a mishap and fell on the ground. He was in pain but the actor brushed it off and continued shooting.
"Such minor accidents keep on happening. I don't even know how I tripped but it wasn't too bad. Nothing to stall the shoot for," Sunil said in a statement.
"Deal Or No Deal" is hosted by actor Ronit Roy. The episode featuring Sunil will be aired on Sunday on &TV.
