Ganguly undergoes second heart operation in weeks

India's cricket chief and former batting star Sourav Ganguly underwent a second heart bypass operation in less than four weeks Thursday, but doctors said he was "fine" after the surgery.

Hundreds of chanting supporters gathered outside the Kolkata hospital where the 48-year old Indian cricket legend was admitted Wednesday after complaining of new chest pains.

Saroj Mondal, one of the doctors treating Ganguly, briefed the media at the hospital.

Ganguly underwent a similar operation on January 3 after being rushed to hospital when he was working out in a gym. 

He was warned then that he could need a second operation.

Youths waiting outside the hospital where Ganguly is resting chanted his name and shouted. 

Shikhar Dhawan and other current members of the Indian cricket team sent messages of support on social media.

Ganguly, a left-handed opener, retired from Test cricket in 2008, having accumulated 7,212 runs including 16 centuries - the first of which he made at Lord's on his debut.

He also scored 11,363 runs in 311 one-day internationals.
