The rain-delayed first one-day international between England and South Africa at Cardiff will begin at 3pm.
It was feared that the game would be a complete washout as the wet weather came down hard at the Swalec Stadium overnight and this morning.
However, with the rain subsiding for now, the umpires have given the go-ahead for a reduced-overs match, with the Proteas fielding first after winning the toss.
The hosts welcome back Ravi Bopara, who returns after taking a break from cricket for personal reasons, while Chris Woakes replaces the rested Stuart Broad.
South Africa make no fewer than six changes to the side that toppled England from the number one Test rankings berth with a 2-0 series victory.
One-day specialists Wayne Parnell, Francois du Plessis and Robin Petersen are among those players who come into the side, with Dale Steyn, Jacques Kallis and Vernon Philander three men to miss out.
England: Cook(c), Bell, Trott, Bopara, Morgan, Kieswetter(wk), Bresnan, Woakes, Swann, Anderson, Finn
South Africa: Smith, Amla, Elgar, De Villiers (c and wk), Duminy, Du Plessis, McLaren, Petersen, Parnell, Morkel, Tsotsobe
