Arshad Warsi, who has been hospitalised after suffering a "bad knee injury", says he has been advised bed rest for two weeks.

"My knee treatment was going on and I have gone and injured it some more. I was doing a Tango dance sequence and my knee gave way during a lift. I have been advised bed rest for two weeks but can't do that so I am on heavy medication now," Arshad told to a media source.

The 49-year-old actor on Wednesday tweeted a photograph showing a wall clock, and wrote: "My view this morning, had a bad knee injury yesterday, in the hospital, trying to fix...I'm doing this."

The 'Jolly LLB' star later shared a photograph of his knee in a navy blue coloured cast and mentioned that he hurt himself doing the Tango.

"'Dard bhari taang' (painful leg) from doing Tango to painful Taangon," a second image was captioned so by the actor, who once had a dance studio.

The 'Ishqiya' actor also shared a photograph along with his doctor and thanked him. "My doctor, Dr Ali Irani, a great physiotherapist and an even greater human being... Thank you," he added.
