Hawks coach Alastair Clarkson has admitted he is concerned by Guerra's ongoing troubles with the tribunal and has urged the former Saint, who earned a two-match ban last week in his first match back from suspension, to avoid making head-high contact with players.
Wary that Guerra was in danger of becoming the next Byron Pickett, who Port Adelaide coach Mark Williams last year described as becoming 'unemployable' due to the attention paid to his physical style, Clarkson urged the 24-year-old to change his ways.
"The rules state you can't make head-high contact and if he wouldn't have made head-high contact, then he wouldn’t have been suspended for two weeks. We've got to address that with him," said Clarkson on Friday morning.
"It's a concern for us because he's a very important player to our side. That physical nature of the way he plays the game is a feature of his play."
"He's more important to us on the field than he is in the grandstand and if that means that he has to pull himself back from some of the contests or just change the manner in which he does charge at a player in that regard then that's the critical element," he said.
"The rules are there to abide by and if you go outside them, then you'll suffer the consequences and he has on two occasions this year. And that doesn't help him and that doesn't help us."
