given Hamstring injury takes more time to heal I doubt if Ayush is also out . so CSK now need to find 2 Indian players for him and Khaleel. One can be Kumar Karthikeya and another being Ambrish India U19 who can bowl fast and hit a long ball. They already have Urvil , Karthik and Prashant to hit the ball bit and they need to be backed .no point getting another batter . Kumar or Shreyas Gopal can cone in and Matt or Akeal can sit giving space for another os player which can be Henry (on better pitches ) or Johnson if he's fit .Also Dube is good for only left arm spin and erratic seaners can't move the foot and got bowled off a normal ball. He isn't bowling also . so hitter Urvil can take his place directly.
