Sydney Roosters firebrand Dylan Napa has escaped sanction for his controversial hit on Brisbane prop Korbin Sims despite being sin-binned on Friday night.

Napa was placed on report for leading with his head in the tackle, which resulted in him being marched at a crucial juncture in their six-point defeat at Suncorp Stadium.

However the match review committee came up with a clean sheet on Saturday.

Roosters coach Trent Robinson vehemently disagreed with the sin-binning after the match, claiming it was merely an accidental head clash.

"He (Sims) stepped off the right, rolled into the head of Dylan, Dylan wasn't even looking sideways and they've called that he intentionally went to knock him out with his head ... it's just wrong," Robinson said.

"It's no one's fault there.

"You're allowed to be physical in our game and if someone wants to step off their right foot to avoid the contact with the left shoulder he's got to go across the head to the other side of the body and he didn't get there ... that's how they clashed heads.

"There's other issues there why we didn't win the game, but that's a gross error and unacceptable at this level."

The development means Napa will be free to play in next Thursday's clash against Parramatta, and avoids any potential suspension that could have ruled him out of the State of Origin opener on June 6.
