Wrestler-actor Dara Singh, who is on life support system and undergoing dialysis, continued to battle for life Tuesday with doctors attending on him saying he was "very critical".

"He is still very critical. Very much with us," Ram Narain, COO, Kokilaben Dhirubhai Ambani Hospital, told Tuesday morning.

The 84-year-old was admitted to the hospital Saturday following a severe cardiac problem, which later led to a kidney malfunction.

In his prime, Dara Singh was a world-famous wrestler and won the title of "Rustam-e-Hind" for his prowess.

He entered the film world in the 1952, and featured in movies like "Watan Se Door", "Daada", "Rustom-E-Baghdad", "Sher Dil", "Sikandar E Azam", "Raaka", "Mera Naam Joker" and "Dharam Karam".

He is also remembered for his portrayal of Hanuman in 1980s TV series "Ramayan".
