Pakistan spinner Sajid Khan on Tuesday reached Australia to play a three-match Test series against the six-time World Cup champions.
Sajid was included in the Test squad as a replacement for Abrar Ahmed, who had suffered an injury.
Pakistan will take on the Pat Cummins-inspired Australia under the leadership of newly-appointed captain Shan Masood on December 14.
Earlier, Abrar Ahmed had been ruled out of the first Test match against Australia starting in Perth from 14 December. During the first- class game against the Prime Minister XI, Abrar left the field of play due to severe pain in his right leg around his knee.
