CSK and Team India all-rounder Ravindra Jadeja, in a recent interview, said that MS Dhoni gave him the name 'Sir Ravindra Jadeja' in 2013 but he still doesn't know why he did it. "He just thought of something...and ke kept tweeting jokes on the name 'Sir Ravindra Jadeja'...(He was inspired by) Rajinikanth jokes that were trending those days," he added.
