Waratahs veteran Stephen Hoiles has blasted the growing use of video replays to scrutinise incidents, warning that rugby is going down the path of the NFL with frequent stoppages threatening the flow of the game.

As the Waratahs prepare to fight foul play allegations against key forwards Tolu Latu and Will Skelton, Hoiles called for Super Rugby organisers to either scrap match officials' extensive powers of video review, or impose a limit on the number of times an incident is replayed.

"I don't think they should be able to go back for foul play," he said.

"I haven't sat down and thought of a clear solution but I think there maybe should be a cut-off time they get – one or two looks at it – but I just felt they were going back too often for too long. The game's not about that.
