The Ireland international, who was due to represent Multan Sultans, is expected to be fit for the start of the Indian Premier League
Josh Little has been ruled out of the remainder of the Pakistan Super League with a hamstring injury.
The Ireland international had been due to represent Multan Sultans but sustained the injury while representing Pretoria Capitals in the SA20.
The 23-year-old has returned to Ireland for treatment and is expected to be fit for his country's ODI series against Bangladesh and the Indian Premier League - he was bought at auction by defending champions Gujarat Titans.
Mark Rausa, Ireland's head of sport science, physiotherapy and medical services, said: "Josh reported experiencing some tightness in his hamstring towards the end of his time in the SA20 League.

"After reporting this to medical staff at Pretoria Capitals, he was sent for an ultrasound scan that was inconclusive.
"Out of an abundance of caution, Josh decided to return home for further tests and treatment with the Cricket Ireland medical team.
"An MRI scan showed no significant injury in the hamstring, but he will remain in Dublin to complete a course of rehab, strength and conditioning and bowling workload management in preparation for the Indian Premier League beginning the end of March, and a subsequent busy period of international cricket for Ireland."
Little, a fast bowler, has made 85 T20 appearances, taking 107 wickets, and has found himself increasingly in demand on the franchise circuit after taking 13 wickets in five outings for Manchester Originals in The Hundred and impressing for Ireland at the past two T20 World Cups.
