The South African is expected to be available for RCB's away game against Kolkata Knight Riders on April 19.
Last year too the 31-year-old Coulter-Nile, who was bought by RCB at the 2018 mega auction for Rs 2.2 crore, pulled out of the tournament due to injury and was replaced by New Zealand all-rounder Corey Anderson.
While last year he was ruled out before the start of the tournament, this season he has been replaced midway through RCB's nightmarish run which has seen them lose six matches on the bounce.
Meanwhile, Steyn, who went unsold in the auction (base price Rs 1.5 crore), returns to the franchise with which he began his IPL journey. Steyn joined the RCB ranks in the inaugural edition when the franchise snapped him up for $325,000 (base price: $150,000).
In a three-year stint with RCB starting in 2008, Steyn featured in 28 matches claiming 27 wickets. His best for the team was 3 for 18 in 2010 while he made just three appearances in the 2009 edition in South Africa due to a thumb injury.
