Calcutta, Dec. 30 :     The Bengal Ranji Trophy team for the Wills one-day qualifier and the four-day meet versus Bihar suffered a setback with star batsman Nikhil Haldipur having to opt out today through what was described by CAB joint secretatry Debdas Banerje as a slipped-disc. Haldipur will be replaced by Mainak Sengupta. Easy for Kumartuli Kumartuli today registered a fine 185-run victory over Tapan Memorial, and Kalighat recorded an equally impressive 158-run victory over Shibpur Institution in their CAB senior division league match.
