The details of Cheika’s issues with the match doctor and the circumstances around the incident are not known with the full judgement yet to be released by the RFU.
He will miss Saturday’s Premiership match away to Newcastle Falcons as a result.
“The panel found that Michael Cheika disrespected the Independent match day doctor in challenging the decision he had made that a player was subject to an IPR (Immediate Permanent Removal),” said Richard Whittam, who chaired the panel.
“Although it was an unusual case because there was a lack of clarity about the decisions made about the head injuries, the decisions of the Independent Match Day Doctor must be respected.
“In this particular case, the appropriate sanction was one of two weeks. The panel mitigated this by suspending one week until the end of the season.”
In response, Tigers’ executive chairman Peter Tom said they will consider an appeal once they receive written reasons for the judgement, and stressed they “would never question the World Rugby HIA [head injury assessment] process, when correctly implemented” and are “rigorously committed to the safety, wellbeing and health of our players”.
Tom added: “Whilst the panel have yet to provide reasons for its decision, the club is particularly disappointed with the disrespectful finding given that multiple witnesses gave evidence at the disciplinary hearing supporting Michael’s version of events.
“The club is also disappointed that despite its request not to do so, the RFU issued a statement announcing the panel’s decision despite the club having not yet been provided with the written judgment and knowing the exact reasons for the decision.”
