The IPL Technical Committee approved the replacement after the New Zealand pacer was ruled out of season 8 due to a foot injury that the medium-pacer picked during the 50-over World Cup.
The Technical Committee of the IPL consists of Anurag Thakur (Hony. Secretary, BCCI), Sourav Dasgupta, Subir Ganguly, Sourav Ganguly and Ravi Shastri.
This will be Arvind's second stint with RCB. The paceman was part of the RCB squad in the 2011 and 2012 seasons of the competition.
He was the highest wicket-taker for the Vijay Mallya-owned side in the 2011 edition, with 21 wickets from 13 games.
