Here are the predicted line-ups:
Team news
Hayden will definitely return at Bailey's expense but what Chennai could well do is draft in Hussey, who has joined the squad for the last part of the IPL. He could well slot in for Oram, who hasn't scored runs or taken wickets. Morkel missed the last game and should come back, meaning Thilan Thushara will go back to warming the bench. Ashwin's excellent figures against Punjab mean he will keep Jakati out as well, but it remains to be seen if Chennai revert to L Balaji - who hasn't been successful in the last couple of games - or give Joginder Sharma another shot.
Chennai Super Kings: 1 Matthew Hayden, 2 Parthiv Patel, 3 Suresh Raina, 4 S Badrinath, 5 MS Dhoni (capt/wk), 6 Jacob Oram/Michael Hussey, 7 Albie Morkel, 8 R Ashwin, 9 L Balaji, 10 Muttiah Muralitharan, 11 Manpreet Gony.
Bangalore confidently fielded an unchanged side for the last two games, and won both. No chances foreseen here. Kallis hobbled off the field after bowling one over last game but didn't look perturbed about missing this one.
Bangalore Royal Challengers: 1 Manish Pandey, 2 Jacques Kallis, 3 Rahul Dravid, 4 Robin Uthappa, 5 Ross Taylor, 6 Virat Kohli, 7 Mark Boucher (wk), 8 Roelof van der Merwe, 9 Praveen Kumar, 10 B Akhil, 11 Anil Kumble (capt).
