Birmingham - Rain delayed the scheduled 6pm local time (1700GMT) toss in the third and final Twenty20 international between England and South Africa at Edgbaston on Wednesday.
South Africa, the world's top-ranked Twenty20 team, lead the series 1-0 after a seven-wicket win at Chester-le-Street last weekend was followed by a no result washout in Manchester on Monday.
These matches come ahead of this month's World Twenty20 in Sri Lanka where England will defend the title they won in the Caribbean two years ago.
