CSK are not known to chop-and-change, but there's a case to bring in Conway for Sam Curran. This could potentially also lead to playing Vijay Shankar as the batting allrounder or Anshul Kamboj as the bowling allrounder, with Impact Sub Rahul Tripathi playing as a floater. 

Chennai Super Kings (probable): 1 Rachin Ravindra 2 Devon Conway, 3 Ruturaj Gaikwad (capt), 4 Rahul Tripathi/Vijay Shankar, 5 Shivam Dube, 6 Ravindra Jadeja, 7 MS Dhoni (wk), 8 Anshul Kamboj, 9 R Ashwin, 10 Noor Ahmad, 11 Khaleel Ahmed, 12 Matheesha Pathirana 

Sanju Samson will likely be their Impact Player for a bowling option. Given the previous game in Guwahati was dominated by Kolkata Knight Riders' spinners, maybe RR could consider bringing in Kumar Kartikeya. 

Rjasthan Royals (probable):1 Sanju Samson, 2 Yashasvi Jaiswal, 3 Riyan Parag (capt), 4 Nitish Rana, 5 Dhruv Jurel (wk), 6 Shimron Hetmyer, 7 Shubham Dubey, 8 Wanindu Hasaranga, 9 Jofra Archer, 10 Maheesh Theekshana, 11 Sandeep Sharma, 12 Kumar Kartikeya/Tushar Deshpande
