Leeds coach Brian McDermott is sweating over the availability of half-back Danny McGuire ahead of Friday's semi-final showdown with Wigan.
McGuire was put on report for a high tackle on Louis Anderson during the Rhinos' win over Catalan Dragons on Friday.
The incident will be considered by the RFL's match-review panel on Monday and McDermott is adamant that McGuire should face no action, arguing that he made accidental contact with Anderson.
"I don't think I'm being biased but that's not a bannable offence," he said. "You can't ban people for unfortunately finding themselves making contact with somebody's head.
"If someone goes out to make contact with somebody's head intentionally, ban them. To keep making that 'mistake', ban them.
"That's what I thought the review panel was for, to try to eradicate repeat offenders, either cynical contact where people are twisting elbow and shoulder sockets or people who just can't get their tackle technique right.
"At the moment with the panel it seems to be a 'one-strike and you're out'. There are very few successes this year. I don't think there has been any not-guilties this year."
