Despite suffering from flu, Sajid Khan had decided not to interrupt his hectic shoot schedule

However, after shooting for 18 hours straight, he felt so sick that a doctor had to be summoned on the sets.

Apparently after filming his Ajay Devgn starrer and editing portions in the night, Sajid reached the sets of a celebrity dance reality show that he judges. A source says, `His condition deteriorated after he sat in the air conditioned studio for long hours.

Sajid ended up calling his physician on the sets and received three injections to stabilise him. The source adds, `After finishing with the editing, Sajid had given his word to arrive on the sets by 10.30 am. We had to force him to eat and now he is resting.`
