Nehra for Zaheer?

There is some bad news for the Indian team, no matter how much the BCCI tries to play it down. Zaheer Khan — the man in-charge of India’s bowling for the forthcoming T20 World Cup is injured and his fitness may be a cause for worry for the entire length of the tournament. In the given scenario, will it make sense for Ashish Nehra to be sent-in as the back-up for Zaheer?
Nehra was in excellent form in the just-concluded IPL2009 and except for one game of the semi-finals, he bowled brilliantly with reasonable if not lightening pace. Further, he too is in the Zaheer mould, trying to move the ball in a subtle manner to keep the batsmen guessing. Further, he would be hungry for getting back to the international arena and this could be an added incentive for him to bowl hard and the conditions in England too would suit him.
