Australia captain Ricky Ponting is a doubtful starter for the Boxing Day Test against Pakistan after an MRI scan confirmed a tendon injury just above his left elbow.

Having begun the series with a genuine chance of becoming the top ODI team in the world, India on Wednesday slipped back to third position after going down 2-4 to world champion Australia in the seven-match home series that concluded in Mumbai on Wednesday.

Strapping Australian all-rounder Shane Watson was awarded the man of the series in the seven-match ODI rubber against India which the visitors won 4-2 after the final game was washed out in Mumbai on Wednesday.

The series already out of their grasp, India will have just pride to play for against the depleted but confident Australia even as steady unseasonal rains threaten to wash out Wednesday's seventh and final cricket one-dayer at the D Y Patil Stadium in Mumbai.

The series might be in their pocket but Australia captain Ricky Ponting on Tuesday said his world champion side would not lower the intensity when they take on India in the inconsequential seventh and final one-dayer in Mumbai on Wednesday.
