DHAKA - India captain MS Dhoni Saturday questioned umpires using earpieces during international matches, suggesting the devices might affect their decision-making on the field. The skipper spoke out after a controversial umpiring decision that saw Pakistan's Khurram Manzoor given not out despite apparently nicking a ball by left-arm pacer Ashish Nehra during India's defeat of their bitter rival during the Asia Cup Twenty20 tournament. "You know all the umpires now have a walkie-talkie and earpiece in their ear," Dhoni said after leading India to the five-wicket win in Dhaka.
