Extended powers of video referee will be used worldwide next year.
The International Rugby Board has announced that following trials, the TMO will be able to advise the on-field referee about incidents of potential foul play and also review up to two phases of play before a try is scored.
Currently, the TMO can be asked to rule only on incidents "in goal" - or over the tryline.
The new powers could be ratified by the IRB council in May 2014.
