Indian captain Mahendra Singh Dhoni was today slapped with a two ODI ban for slow over-rate during the second cricket one-dayer against Sri Lanka, giving a major blow to the home team's prospects in the ongoing five-match series.International Cricket Council's match referee Jeff Crowe imposed an immediate two match suspension on Dhoni for slow over-rate after conducting a hearing last night.The BCCI said opener Virender Sehwag has been named the captain for the next two one-dayers in Cuttack on 21st December and Kolkata on 24th December. The Indian players have been penalised 40 per cent of their match fees. The thrilling second one-dayer ended about 45 minutes after the scheduled finish time because of frequent discussions between the Indian players during the closing stages of Sri Lanka's chase.
