Former referee Steve Conroy thinks it is "mission creep" with VAR in Scottish football before new changes to the laws for the upcoming World Cup.
VAR was introduced in Scotland almost four years ago but has frequently been criticised by fans, players, managers and former players.
Now there could be more changes to the scope of technology as football's law-making body the International Football Association Board (Ifab) backed plans to increase the powers of VAR.
For this summer's World Cup in America, VAR will be allowed to intervene on second yellow cards and the awarding of corners, provided the process doesn't slow down the flow of play.
Ifab has also expanded the countdown rule around goalkeepers where they have eight seconds to release the ball from their hands to include goal kicks and throw-ins.
But former referee Conroy thinks involving the technology in more decision-making is bad news for the game.
"It's inescapable that there is more and more mission creep with VAR," he told the BBC’s Scottish Football Podcast.
"The authorities seem hell-bent on using it more and more and relying on it and I think that is to the detriment of football.
"I know Ifab are talking about getting them involved for corners and second yellows and all that sort of stuff. As [Celtic interim manager] Martin O'Neill said, soon enough we'll just referee from a port-a-cabin somewhere.
"And this is all happening at the same time as every football supporter survey tells you that they just want it binned."
