Last year, the tournament involved twelve teams and this year four more teams would be added, according to BCCI CAO, Prof Ratnakar Shetty. "We will send out invitations to 20 or 21 corporates and then decide on the teams. All these teams should have players on their rolls and not on contract. The proposal is for a level playing field and that no team can have more than four BCCI contracted players in the playing eleven," he explained. "The teams would be split into four groups of four each," he added.
