There were reports that the "CityLights" star would be seen making a special appearance with Aamir, who worked with him in "Talaash".
"All these reports about me in 'Dangal' are rumours," Rajkummar told PTI.
The National-award winning actor is all geared up for "Aligarh", which releases this Friday. It is based on the real life story of a professor Dr S R Siras, who was fired from his position for his sexuality.
Directed by Hansal Mehta of "CityLights" and "Shahid" fame, the film stars Manoj Bajpayee.
