Livingstone had pulled out of the tournament due to bio-bubble fatigue last month.
“Rajasthan Royals have signed South African fast bowler Gerald Coetzee as a replacement for England’s Liam Livingstone for the remainder of the VIVO Indian Premier League (IPL) 2021,” an IPL media release said.
The 20-year-old Coetzee has played eight T20 matches so far and has taken nine wickets at an average of 23.33 in the format. He has represented his country in two under-19 World Cups.
The Royals are slated to take on Sunrisers Hyderabad on Sunday.
