Afridi thanked the Heat and fans on social media, saying he hopes to return to the field soon while supporting the team from the sidelines.
Brisbane Heat will review his condition after their next match against Adelaide Strikers.
This season marked Afridi’s BBL debut alongside fellow Pakistanis Babar Azam, Mohammad Rizwan, and Haris Rauf.
However, he played only four matches, taking two wickets at an economy of 11.19. In his first game, he was removed from the attack for two waist-high full-tosses.
He reportedly injured his right knee while bowling in Adelaide Strikers’ chase on December 27.
