NSW Origin prop Brett White is set to join his suspended Storm captain Cam Smith on the sidelines for next Sunday's grand final after knocking out former flatmate Ben Ross for the second time this season in last night's defeat of Cronulla.

White, who told the Herald in the lead-up to his first meeting with Ross since the pair were sent off in round two that he had learnt the error of his ways, was placed on report for striking his front-row opposite with an elbow.

The seventh-minute incident, which continued the bad blood between two teams, whose players appear to share their coaches' dislike for each other, resulted in a dazed Ross being taken from the field. He did not return until late in the first half.

Running the ball near the Sharks line, White appeared to legitimately bump off Ross with his forearm but then raised his arm and had another two attempts. Replays suggested that while the initial point of contact might have been Ross's chest, he was then struck in the head by White's elbow.

After coming to the aid of Cooper Cronk when the Melbourne halfback was felled by Ross in the round two clash between the teams at Olympic Park, White received a four-match ban and he now faces another striking charge when the match review committee meets on Monday.

Because of his previous suspension, White is in a similar situation to Smith, who this week received a two-match ban for a grapple tackle after pleading guilty to the same offence earlier this season.

Even a grade-one striking charge - carrying a base penalty of 125 demerit points - would rule White out of the grand final, as he has carry-over points from the earlier ban and will also attract a 50 per cent loading.

Cronk and second-rower Michael Crocker are also set to come under scrutiny for a 68th-minute lifting tackle on Cronulla halfback Brett Kimmorley but the incident was not put on report and they should escape a charge.

Despite the lead-up to the match being dominated by headlines about the Storm's wrestling tactics, there was only one penalty in the match for a grapple tackle, but veteran Melbourne centre Matt Geyer is unlikely to have anything to worry about.

Touch judge Jeff Younis reported the 27th-minute incident to referee Tony Archer but they were unaware which Melbourne player had made the tackle and issued the Storm a general caution.

The win enables Geyer the chance to enjoy a fairytale end to a career that started with the Perth Reds in 1997 before he moved to Melbourne the following season as a foundation player.

However, the result was a disappointing farewell to Cronulla for Geyer's scrumbase partner at Melbourne in the 1999 grand final win over St George Illawarra.

Kimmorley is being replaced next season by Trent Barrett, the player who fed the scrums for the Dragons on that occasion, and will join the Bulldogs after being offered a release by Cronulla.

Veteran prop Adam Peek is also leaving the Sharks to join Welsh Super League club Celtic Crusaders on a one-year contract, while winger Misi Taulapapa is unsigned and has been linked to a move to South Sydney.

In addition to Barrett, the Sharks have signed Sydney Roosters and Australian second-rower Anthony Tupou.
