The much-anticipated comeback of Ambati Rayudu will be a shot in the arm for a Chennai Super Kings (CSK) under-pressure when they take on Sunrisers Hyderabad (SRH) here on Friday in the IPL, who have shown resilience after early setbacks. Rayudu, hero of the opening IPL victory of CSK against Mumbai Indians, missed out due to mild hamstring injury and after the Caribbean Premier League where he did not bowl in the last two games, Bravo has also been carrying a niggle of a similar nature. “Both Rayudu and Bravo are available for selection,” CSK CEO KS Viswanathan told a leading media house on Thursday.
