The Knights faced disappointment as Raiders scored first in the second half after a tie.
The Knights were dealt a cruel blow after putting forward a spirited first half display against minor premiership favourites, Canberra.
With the score 18-18, Tom Starling was first to score in the second half for the Raiders with a four-pointer that looked almost too good to be true.
On the fifth tackle, Jamal Fogarty kicked to the corner with Xavier Savage tackled by Fletcher Hunt but getting a pass away. The ball went back to the middle of the field and Starling ran through a huge hole.
