Scotland's Nathan Hines is determined to be on his best behaviour in the Calcutta Cup clash with England on Saturday.
The Australian-born lock has been in trouble for his actions off the ball in this year's RBS Six Nations tournament.
First he was sin-binned against Wales for lashing out at Lee Byrne and then in the game with Ireland two weeks ago he cost his team a crucial penalty for taking a swing at Denis Leamy.
Now Hines, who plays his club rugby in France for Perpignan, is looking to stay out of trouble at Murrayfield and let his rugby do the talking.
"I think the flak I have copped is fair enough," he said. "I watched the video of the Irish game for the first time earlier this week and it does look pretty bad.
"I don't regret trying to get the ball back but I shouldn't have put myself in that situation where I was at risk of giving away a penalty.
"I've been quite hard on myself over these two incidents. I don't want that to be the only thing people remember me by, so it is something I am conscious of and I'll try not to put myself in that sort of situation again."
Hines knows any indiscretions against a team that includes a kicker like Jonny Wilkinson could prove costly.
"You can't afford to give away silly penalties against any team in this tournament - and against England it could be disastrous," he said.
"Teams have found to their cost in the past that you give them a penalty here and a penalty there and before you know it they are out of reach."
However, the second-rower does believe that Scotland can cause an upset after an improved performance last time out against Ireland.
"We aren't going to get that many chances against England so we can't afford to waste any of them," Hines added.
"The preparation has gone really well and there is a feeling among the guys that it is now or never, so it should be interesting.
"It's always good to beat England because it's a tournament within a tournament with the Calcutta Cup."
