Graeme Swann will play no further part in the one-day series against Australia after it was announced that he would be rested for the final two matches.
England have decided to call up James Tredwell to cover the Nottinghamshire spinner who has been suffering slightly with a sore elbow.
Warwickshire fast bowler Chris Woakes will also be added to the squad for the two remaining games at Chester-le-Street on July 7 and Old Trafford on July 10.
England are 2-0 up in the series and were hoping that they would be able to complete a series whitewash which would have seen them overtake Australia at the top of the One Day International rankings.
However, the wash-out at Edgbaston yesterday meant that England will have to settle with trying to earn a series win.
"We had earmarked the fourth and fifth matches in this series as an opportunity to rest Graeme regardless of the result at Edgbaston as we have to consider our preparations for the Investec Test series later this month," revealed national selector Geoff Miller.
"Graeme has some pain in his elbow at the moment and we feel that an extra week's rest will allow his elbow to settle. Chris Woakes replaces Jade Dernbach in the squad who has been ruled out with a side strain.
"We have played some very good cricket in the last week to lead this NatWest Series 2-0 and will need to continue that form if we are to win our seventh straight series on home soil."
England squad: Alastair Cook (Essex) (Captain), James Anderson (Lancashire), Jonny Bairstow (Yorkshire), Ian Bell (Warwickshire), Ravi Bopara (Essex), Tim Bresnan (Yorkshire), Stuart Broad (Nottinghamshire), Steven Finn (Middlesex), Craig Kieswetter (Somerset), Eoin Morgan (Middlesex), Samit Patel (Nottinghamshire), James Tredwell (Kent), Jonathan Trott (Warwickshire), Chris Woakes (Warwickshire)
