Pratt was called "extremely soft" and "pathetic" by Lewis' teammate Campbell Brown for collapsing to the ground after the alleged punch by Lewis.
"If you're going to be hard at the footy and put your head over the ball, that's what being tough is," Pratt said in response to Brown's comments.
Rawlings concurred with Pratt's assessment.
"Hardness is really about when the ball is in play and putting your head over the ball," Rawlings said.
"They probably had a couple of undisciplined things off the ball, so I don't think that's anything to do with toughness."
