Former Port Adelaide midfielder Kane Cornes has slammed Hawthorn defender James Sicily, labelling the young Hawk as a "sook."

Sicily had 26 disposals and nine marks and was one of Hawthorn's best in their eight-point loss to the Swans at the MCG, but it was an incident on the final siren that caught Cornes' eye.

The Hawk was seen arguing with the umpires immediately after the final siren, and that seemed to be the last straw for Cornes.

“I think he’d be waking up embarrassed this morning,” Cornes told SEN’s Crunch Time.

“I think we’re prepared to let the one go last week where they’re winning easily, he’s playing well, he gives Daniher the high-five – a bit cheeky, but nothing to see there, he’s a character, we want characters in our game.

“It’s all well and good to do the high-fives and patting Luke Parker on the chest and waving to him after that incident when you’re two goals up and you think you’re going to win the game.

“Then 10 minutes later to see him complaining to the umpire like an absolute sook.”

Sicily has already been suspended twice this season, and Cornes believes it's not a great look for the 23-year-old.

“When he’s losing against North Melbourne he steps on somebodies leg,” Cornes added.

“We shouldn’t be talking about this guy every week, but we are.

“When things aren’t going his way, he’s not good at coping.”
