Hyderabad: Depleted by the absence of some high-profile cricketers, IPL champions Kolkata Knight Riders will have a tough task at hand when they lorn horns with the formidable Chennai Super Kings in the opening Group 'A' match of Oppo Champions League T20 here tomorrow.

Buoyed by its thumping success in the IPL T20 tournament this year, KKR is raring to go for the kill in the Champions League but their build-up to the tournament has been plagued by injuries to Chris Lynn and Morne Morkel and the absence of Shakib Al Hasan, who failed to get an NOC from the Bangladesh Cricket Association.
