KARACHI:-Former ICC president Ehsan Mani has backed the decision of the sport's governing body to persist with the Decision Review System (DRS), which according to him has helped in reducing the mistakes of umpires. "I think they are only minor issues now related to the technology use in the DRS but they are not serious enough to warrant suspending the use of the UDRS," Mani said. Mani has been visiting Pakistan to supervise the bidding process by the Pakistan Cricket Board for the sale of broadcasting rights of the upcoming home series against South Africa and Sri Lanka in the UAE. –Agencies
