Simmering tension between last year's NRL grand finalists spilled over when Sydney Roosters coach Ricky Stuart hinted Penrith was playing games over the severity of Luke Swain's injury.

Swain lost four teeth and suffered a fractured jaw in a high tackle by Roosters hooker Stuart Webb during Friday night's grand final rematch at Aussie Stadium - an incident which led to Webb being suspended for three weeks.

That prompted Stuart - who also lost Adrian Morley to suspension - to take a thinly veiled swipe at the Panthers.

Stuart said he had heard conflicting reports over the nature of Swain's injury.

"We hear differing reports like that Luke Swain said he would be able to play this weekend if he can get a special mouthguard made," Stuart said.

"Then we hear the Penrith club is loading up and ready to send in medical reports if we did try and fight the charge.

"So you do hear differing reports on the extent of the injury."

Roosters chief executive Brian Canavan met with match review commissioner Greg McCallum on Monday to discuss the grading of the incident.

McCallum admitted the extent of the injury had played a part in the grading, but said Swain's ability or inability to play was not a factor.

However, Penrith chief executive Shane Richardson reacted angrily to Stuart's comments, saying he objected to the intimation that nothing was wrong with Swain.
