The governing council received a few requests from the concerned cricket boards which forced the International Cricket Council to extend the deadline by six days.
"All participating men's teams must have its 15-player squads into the ICC no later than Friday 24 August 2012," ICC stated in a release.
"The date for the women's teams to submit its 15-player squads for the ICC Women's World Twenty20 Sri Lanka 2012 remains unchanged and must still be submitted to the ICC by Sunday 26 August 2012," it added.
With ICC's deadline extended until 24 Aug, England makes Pietersen wait more to announce the final 15-member squad as the cricketer awaits a recall to the T20 squad after apologizing for sending derogatory texts to South African players.
Kevin Pietersen who announced his retirement from limited overs format recently has been in news ever since that announcement as he desires to make a comeback to the T20 side to defend England's T20 title in Sri Lanka.
