Richmond coach Damien Hardwick has slammed the score review system, calling it an "embarrassment".

The Tigers had a goal taken off them in during the clash with the Saints, when a review of what was initially deemed a goal was overturned.

Triple M's Wayne Carey said on air the vision showed it should have been a goal.

Hardwick more than agreed with the sentiments.

"We ask to trust and respect the umpires. How about we back the goal umpire in?" he asked.
