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.
"Dangal" is based on the life of wrestler Mahavir Singh Phogat, who taught wrestling to his daughters Babita Kumari and Geeta Phogat.
