The AFL's score review system again came under heavy fire on Saturday night when a goal was overturned, possibly costing Adelaide a place in the finals series.

Players from both sides thought it was a goal, Richmond coach Damien Hardwick thought it was a goal, and the umpires thought the same when the ball was returned for a centre bounce after Adelaide's Rory Sloane appeared to sneak the ball through at the 29-minute mark of the third term.

However, the goal was reviewed and it was deemed the ball had touched the post.

The key factor that has again brought the system under question was the fact the same camera set-up was not in place as at other grounds in Melbourne, and many believed because the decision was inconclusive it should have stayed as a goal as determined by the goal umpire.
