Cronulla centre Nigel Vagana is confident he won't have any NRL judiciary worries heading into next Friday's Anzac Test despite coming under scrutiny for a high tackle in Friday night's match with Penrith.

The New Zealand international was penalised for a high shot on Penrith's Bryan Norrie late in the first half of the Sharks' 40-12 win at CUA Stadium, but Vagana said he had few concerns about the incident after the game, believing the Panthers replacement had slipped into the tackle.

Norrie stayed down for close to a minute, allowing the video official to have a look at the incident and instruct referee Sean Hampstead to award the Panthers a penalty.

"Sean was right there and he didn't put it on report," said Vagana.

"If (Norrie) had got up and played the ball I think they would have just played on with the game, so I don't think anyone was too concerned," Vagana said.

"He was running at me, I made the tackle, I got up and he didn't. Well he got up slowly."

Norrie later left the field with an ankle injury with Panthers coach John Lang saying he will likely be in doubt for next week's match with North Queensland.

Cronulla coach Stuart Raper said he didn't think Vagana had anything to worry about.

"The player really dipped into the tackle and it was really hard for Nigel to adjust his technique that late. There was no swinging arm, I know the shoulder comes into it, but I hope the judiciary won't think that way.

"But we'll have to wait and see. I'm not the judiciary."
