India's woes in the ongoing series against Australia compunded Sunday with embattled skipper Mahendra Singh Dhoni being handed a one-match ban for slowover rate in the Perth Test. That rules him out of the fourth Test in Adelaide. Dhoni was penalised because he failed to bowl the full quota of overs. India fell 2 overs short. Vice-captain Virender Sehwag will lead the side in the final Test which begins on January 24. India have now suffered seven overseas defeats in a row starting with the Lord's Test in England last summer.
