Raiders suffer costly loss as Ricky Stuart laments 'brain explosion'

The Dragons beat the Sharks 24-16 in a thrilling derby victory at Kogarah, as the Knights ended the Raiders season with a 30-24 victory in Canberra.

Trailing 26-24 in the final 10 minutes of the contest, the Raiders were awarded a penalty after Dane Gagai and Corey Horsburgh tangled at a play the ball.

Instead of having a kick at goal to level the scores though, Horsburgh slapped Gagai over the head, resulting in the penalty being overturned.

Ricky Stuart was livid, calling the incident "a f***ing brain explosion".

"We should have gone 26-all and there was a brain explosion," Stuart said.

"It was a f***ing brain explosion, and we lost the opportunity."

Stuart was under no illusions that his forward was in the wrong, either.

"Of course it was [a sin bin]," he said.

"There was one last week. Everyone knows that, you're not allowed to do that. It's in the rules. It's been in the rules for the last many, many years."

The Raiders fans may have felt hard done by after Gagai was not sin binned earlier in the half following a tip tackle on Horsburgh, for which he was only placed on report by referee Ashley Klein.

In the late match, St George Illawarra dealt Cronulla Sutherland's top-two finals hopes a hammer blow with a spirited 24-16 victory.

Recording only their third win of the season and just their second derby success in their last 13 against the Sharks, the Dragons are still in the hunt to avoid the wooden spoon.

Addin Fonua-Blake could face a spell on the sidelines for the Sharks, after being sin binned and placed on report for nasty shoulder charge on Dragons forward Hamish Stewart.

Jesse Ramien left the field with a suspected pectoral injury and Ronaldo Mulitalo also played out the second half under an injury cloud on a bad afternoon for the premiership aspirants.

Meanwhile, Storm halfback Cameron Munster was given a one-match ban for dangerous contact against Sea Eagles forward Taniela Paseka, only to have that overturned a couple of hours later.

Munster was charged after making contact with the side of the knee of the Sea Eagles prop as the third man into a tackle during the first half of the game, which the Storm came from behind to win.

The NRL judiciary later amended the charges after a medical report from Manly showed Paseka's injury was not as severe as it was initially thought.

Instead of a week off, Munster can now accept a $750 fine for a grade one dangerous contact charge.
