( CNN ) -- England will make their defense of the World Twenty20 title without gifted batsman Kevin Pietersen , who was omitted from their 15-man squad Tuesday . Pietersen was man of the tournament in their triumph in the Caribbean two years ago , but is at odds with teammates and the England management for `` provocative '' texts sent to opposition South African players . The 32-year-old was left out of the third Test against South Africa at Lord 's , which ended in a 51-run defeat , despite scoring a superb century in the previous match of the series . He has apologized for the text messages , which allegedly criticized England captain Andrew Strauss , but it has not been enough to earn him a recall to the England fold . `` Kevin Pietersen 's future involvement is still being determined and he was therefore not considered for selection in either squad , '' national selector Geoff Miller told the official England and Wales Cricket Board website . South African born Pietersen averages nearly 50 runs per innings in Test cricket and is renowned for his ability to score quickly in one day internationals and the Twenty20 format . But earlier this year he made a shock announcement to retire from one-day internationals and Twenty20 matches for England . After his superb 149 in the second Test against South Africa , Pietersen cast further doubt on his future by saying `` obstacles '' must be overcome for him to continue playing . He was believed to be referring to a fake Twitter account which portrayed him in unflattering terms and was being followed by several of his teammates . But Pietersen was soon using YouTube to announce that he was available again for England in all forms of cricket . It was not enough to earn him selection for the final Test where England lost their No.1 status and his exile has now continued . Pietersen 's close friend , the Australian cricket legend Shane Warne , said Tuesday that it was a `` tragedy '' that he would not be playing for England . `` There 's a bit too much ego at the ECB ( England and Wales Cricket Board ) , there 's no give or take or compromise , '' Warne told a press conference in Sydney . `` If he does n't sign his England contract , if he does n't play for England again , I just think that 's a tragedy . '' But Warne added : `` Kevin Pietersen has to put his hand up and say ' I 've conducted myself in a pretty ordinary fashion , too ' . '' England 's squad contained few surprises , with eight survivors of the squad which won the trophy two years ago . Jonathan Bairstow , who scored 95 and 54 in stepping in for Pietersen at Lord 's , is included . `` We are very much looking forward to beginning the defence of our World T20 title next month , '' said Miller .
