London: Front-foot no-balls will be called by the third umpire in the upcoming England-Pakistan one-day international series, as part of an International Cricket Council (ICC) trial scheme.
The TV umpire will have a split-screen view of the four side-on cameras.
This will allow him to signal the on-field officials via a vibrating watch within a few seconds of the delivery.
On-field umpires will not call front-foot no-balls without the TV umpire's advice unless cameras are unavailable.
The five-match series, which begins in Southampton on Wednesday, will be the first in which the third umpire has been given such authority.
