"Yes, Dhoni has had a successful knee surgery at the Kokilaben Hospital in Mumbai on Thursday. He is doing fine and will be discharged in a day or two. He would be resting for a few days before his extensive rehabilitation starts. It is now expected that he would have enough time to get fit to play in the next IPL," a source close to CSK management told PTI on conditions of anonymity. Dhoni had played the entire season with heavy strapping on his left knee and while he looked absolutely fine during wicket-keeping, he came into bat as low as No. 8 at times and didn't look in his element while running between the wickets. On Wednesday, CSK CEO Kasi Viswanathan said that whether Dhoni wants to undergo surgery will be completely the iconic captain's call.
