Rahane, who is yet to get a game in the tournament, could find himself playing at his home ground in Mumbai if Yuvraj doesn't recover fully in time for the last-four game on March 31.
Captain Mahendra Singh Dhoni, speaking after the six-wicket win last night, said he is open to changes in the playing XI if the conditions demand.
"I don't know whether we should make changes but it is possible, depending on the wicket. We have to see Yuvraj's injury as well. We would definitely like to have a replacement ready if the physio says his injury is bad," he said.
Shane Watson, who retired with the Mohali loss, was asked about his former IPL teammate Rahane not finding a place in the XI.
"Jinks (Rahane) I think is a very good player. But where do you fit him with the quality of Indian batting line-up? He certainly knows how to score in all conditions," Watson had said.
