Abrar, who has picked up 38 wickets in his six Tests so far, was shaping to be the lead spin bowler for Pakistan as they attempt to win their first-ever Test series in Australia. If he is to spend an extended period of time on the sidelines, that will put the onus on Noman Ali to lead the spin attack in conditions that may not suit his style of bowling. The left-arm orthodox bowler has typically thrived on slow and low pitches, picking up 47 wickets in 15 Tests.
