During the interval between innings, the highest on-line bidder in an on-line auction will receive 15 minutes of one-to-one coaching from India batting great Tendulkar before walking out to the middle at Lord's to face an over from Australia leg-spin legend Warne, the world's leading Test wicket-taker.
Tendulkar will remain at the non-striker's end to offer advice and Lord's owners MCC will commission a commemorative photograph of the event, which will also be televised.
MCC president Tom Graveney, the former England batsman, said: "This is an incredible opportunity for one cricket fan to live a dream - to walk out to bat against the world's leading Test wicket-taker at the Home of Cricket in front of the Lord's crowd and a worldwide television audience.
"In addition, they will be able to prepare for the experience by receiving personal coaching from one of the world's greatest ever batsmen.
"We hope that this amazing opportunity, which has been made possible by the generosity and co-operation of Shane and Sachin, will raise a significant additional sum for the Tsunami appeal."
The auction will begin at 1400 hours (GMT) on Wednesday, June 8 and close at 1400 hours (GMT) on Saturday, June 11.
Bids can be placed online at www.cricketrelief.org with the winner also receiving two tickets to the match.
