Deepak Chahar opens the bowling for CSK, while K L Rahul and Quinton de Kock are the two openers for LSG, who will be aiming to repeat their match-winning opening stand against the same opponents earlier in the tournament.
Meanwhile, CSK have made a change as Shardul Thakur comes in as the Impact Player in place of Rahane.
Chahar strikes a vital blow in the first over of the innings. De Kock is bowled off an inside edge off the third ball as he tries to hit Chahar through the off-side.
An early blow for LSG as de Kock walks back for a three-ball duck.
Marcus Stoinis guides the fifth ball to thirdman for a single. Chahar gets some sharp inswing as Rahul manages to hit the last ball to mid-on.
Superb start from Chahar as he concedes just a single while making the breakthrough in the first over.
