South Sydney have put a number of late or high challenges on Nathan Cleary after kicking the past couple of years.
It comes after the Panthers recently discovered that Rabbitohs officials made a series of complaints to the NRL after Penrith's emotion-charged victory against Souths in round 23.
The Rabbitohs asked the governing body for a please explain as to the way Penrith used “blockers” to restrict the ability of South Sydney markers from putting pressure on Cleary’s kick.
TheHerald has learned that Rabbitohs coach Wayne Bennett,when coaching Queensland during last year's State of Origin series,also raised similar concerns with the tactics used by NSW to protect Cleary.
The Rabbitohs identified Isaah Yeo was guilt of an illegal block that went unnoticed by the referees when the two teams squared off at Suncorp Stadium three weeks ago,a game in which Cleary had ample time to put up his trademark floating bombs which led to several mistakes from Josh Mansour and Latrell Mitchell.
The Rabbitohs believe Penrith’s Isaah Yeo moves backwards to block Cameron Murray from putting pressure on Nathan Cleary during the round 23 game a fortnight ago.
Images from previous meetings between the two teams over the past two seasons show a number of incidents over which the Panthers raised concerns.
The most alarming was a high shot from Cleary's NSW Blues teammate Cameron Murray after a kick last year.
