Cape Town - Cricket South Africa (CSA) has announced two enforced changes as well as a rotational change to the Proteas squad for the remainder of the five-match ODI series against Sri Lanka.“Hashim Amla has been forced to stand down because of family responsibilities while Rory Kleinveldt has a relatively long-term injury,” commented CSA selection convener Andrew Hudson.In addition, the team management has decided to rest Jacques Kallis. The respective replacements are Highveld Lions batsman Alviro Petersen, Cape Cobras all-rounder Vernon Philander and Warriors batsman Colin Ingram.“Both Petersen and Philander showed excellent form in the recent Sunfoil Test series against Sri Lanka and they have also represented the Proteas in the ODI format before so I don’t anticipate their having any problems adapting to 50 overs cricket,” Hudson added.“Ingram has also been in top form in domestic cricket and was a member of the squad that went to the World Cup last year after making a century on debut against Zimbabwe.“Although we are sad to lose players such as Amla and Kallis I see this as an opportunity to try out our options. There are still places up for grabs in our ODI squad and I must say I am excited to see the talent coming through our development pipeline.”Petersen played the first of his 14 ODIs against Zimbabwe in 2006 with the most recent one being in the West Indies in 2010.Philander made his ODI debut against Ireland at Belfast in 2007, taking his best figures of 4/12 on debut. He has played 7 ODIs to date, the most recent being against England at Lord’s in 2008.Ingram made his ODI debut against Zimbabwe in 2010 and has played 12 matches to date at an average of 41.55 including two centuries. His most recent appearance was against Ireland at the 2011 World Cup.Proteas squad: AB de Villiers (Titans, captain), Johan Botha (Warriors), JP Duminy (Cape Cobras), Faf du Plessis (Titans), Colin Ingram (Warriors), Albie Morkel (Titans), Morne Morkel (Titans), Wayne Parnell (Warriors), Alviro Petersen (Highveld Lions), Robin Peterson (Cape Cobras), Vernon Philander (Cape Cobras), Graeme Smith (Cape Cobras), Dale Steyn (Cape Cobras), Lonwabo Tsotsobe (Warriors).
