Tendulkar edged paceman Shaun Tait to wicket-keeper Brad Haddin in the 19th over and had started walking when umpire Marais Erasmus called him back while he confirmed the legality of the delivery.[break]
Once the replays showed that the delivery was legal, Tendulkar walked away, much to the disappointment of the crowd which packed the Sardar Patel stadium for India´s do-or-die encounter.
Tendulkar, 37, looked in sublime form during his 68-ball innings, hitting seven fours in his 94th one-day half-century.
The veteran batsman, playing his sixth World Cup and probably his last, also completed 18,000 one-day runs in the process.
India were chasing 261 for a victory which will book them a semi-final clash against arch-rivals Pakistan in Mohali on March 30.
