Gambhir has led the team to IPL glory in 2012 and is again set to lead the team for the fourth straight season while Narine has been one of the biggest assets for the Kolkata franchise.
KKR CEO Venky Mysore said, "We are delighted that we have managed to retain two of our key players. We hope to build a competitive and exciting squad. The challenges of salary cap deductions and the retention rules did not allow us to retain more of our original team, who made us proud over the past three years."
KKR will have 38 crores of salary cap space and two retention cards going into the auction in February.
