South Africa will not be touring Pakistan in the proposed one-week window from March 22-29 to manage players’ workload.
The planned tour will be rescheduled after the two boards find a new window.
South Africa, who are also touring India for three ODIs, were looking to visit Pakistan for three T20is after the conclusion of the Pakistan Super League on March 22.
Rawalpindi was the proposed venue but as it stands now, the tour is postponed and an alternate window to play the games is yet to be decided.
The proposed three-match T20i series was over and above two-Test and three-T20i series in january, next year, which is part of the future tours programme.
