Former India batsman Vinod Kambli, once considered as talented as his school friend Sachin Tendulkar, was admitted to a Mumbai hospital on Friday with a suspected heart attack, media reports said.
Kambli, 41, had undergone angioplasty on two blocked arteries last year and appeared to suffer a heart attack on Friday morning, NDTV news channel and Rediff website said.
There was no immediate comment from the hospital.
Kambli shot to fame in 1988 when he shared a then world record 664-run partnership with Tendulkar in an inter-school match in Mumbai, with both batsmen making unbeaten triple centuries.
While Tendulkar retired earlier this month as the world's leading run-maker in both Test and one-day cricket and an unprecedented 100 international centuries against his name, Kambli faded after a bright start.
The flamboyant left-hander hit two double-centuries and two hundreds in his first eight Test innings after earning a debut in 1993, but another three-figure knock in Tests eluded him.
Kambli played the last of his 17 Tests in 1995 before he had turned 24, finishing with 1,084 runs at an average of 54.20.
He also scored 2,477 runs in 104 one-day internationals with two centuries.
