Bulldogs halfback Brett Kimmorley says he has nothing to prove to Cronulla when he takes on his former team for the first time at ANZ Stadium on Sunday.

Kimmorley spent seven happy years with the Sharks before being shown the door at the end of last season by coach Ricky Stuart, but is treating Sunday's showdown as just another game.

"I think I left the club on good terms .. I don't feel like I having anything to prove," he said.

The 32-year-old former Test and Origin star also said he will not be going out of his way to talk to any of his ex-teammates before the game.

"I don't really care if I talk to them or not, I don't generally get that pumped up before a game, if I come across them I will say g'day," he said.

"I still live in Cronulla so there is a fair chance I will see some of them, so I will of course have a chat if I do."

Despite having lost their last two games and being hit by season-ending injuries to Ben Ross and Brett Kearney, plus key playmaker Trent Barrett almost certain to be sidelined on Sunday by a neck injury, Kimmorley refused to accept it is a good time to play the Sharks.

"Ricky will not like the fact that they lost to Newcastle and will feel they could have beaten the Dragons as it was a game they had every chance of winning," said Kimmorley.

"Knowing what Ricky is like he will have their intensity up this week and they will probably fancy their chances against our forwards and we have to make sure we match their aggression."

Despite his initial disappointment of not being offered a new deal by the Sharks, Kimmorley said he had no regrets about his move to the Bulldogs and no problem with Stuart.

"I have moved on and so have the Sharks and I am more than happy where I am," he said.

With events off the field making the headlines so often this season, Kimmorley admitted the story of a car park bust-up between Bulldogs trio Jamal Idris, Lee Te Maari and Ben Barba is disappointing.

All three have been stood down from all football this weekend for breaching the club's code of conduct, with Te Maari stood down for two weeks as a consequence of previous breaches.

"As a club and as a game I don't think we can be any clearer on what our expectations are in relation to player behaviour," Bulldogs chief executive Todd Greenberg said in a statement on Wednesday.

"These three players will now have some time free of football to think over their actions."

Following an independent investigation into an incident involving Daniel Holdsworth in Cronulla last weekend, the Bulldogs have determined no further action is necessary.

"Our off-field image is pretty good at the moment, membership is up and a lot of effort has gone into that ... and the club and board have acted in the way they see fit," Kimmorley said.

"As far as we are concerned it is over and done with, but I think many things now are being blown out of proportion because of what has happened this season.

"But we are still making mistakes, we have to pull our heads in and stop these little stories becoming large stories."
