New Delhi: Actor Randeep Hooda, who collapsed on the sets of Salman Khan-starrer "Sultan" on Sunday evening following a severe attack of appendicitis, was scheduled to undergo surgery at Fortis Hospital here on Monday. "Randeep had been in acute pain for some time, but he is known for his professionalism so he ignored it to complete the shoot on time.
