Indian batsmen Virender Sehwag and Gautam Gambhir are injury doubts for Monday's fourth one-day game against Australia in Mohali.

Opener Sehwag was struck on his left foot by a Peter Siddle yorker and Gambhir was hit below the ear by a pull shot from Australian skipper Ricky Ponting during India's six-wicket win in the third ODI in New Delhi.

Their availability will be only decided before the game and wicketkeeper-batsman Dinesh Karthik has been named as cover, the Board of Control for Cricket in India said in a statement.

India lead the seven-match series 2-1.
