Munster have stressed they followed the right protocols in treating Conor Murray's head injury despite the EPCR calling for a review of the incident.
Murray clashed heads with Glasgow's Tim Swinson in their Champions Cup match last weekend and left the field to undergo an assessment of the injury.
Murray passed the assessment and Munster communications manager Fiona Murphy told the Irish Examiner he also completed the HIA 2 and 3 after the game, but the EPCR have asked its medical advisory group to convene an untoward incident review to investigate the timeline of events.
"We’re working with EPCR and anything to do with player welfare is welcome from our point of view," Murphy said.
"We’ll work with EPCR on anything like that. Everything we did (in treating Murray) was in keeping with World Rugby guidelines in terms of timings and the medical processes, as it has been with every head injury."
Former Ireland team doctor Cliff Beirne told RTÉ Radio’s Morning Ireland programme HIA protocols should be conducted by independent medical practitioners.
"I personally have to endorse the integrity and the commitment to player welfare of all the doctors and physiotherapists involved in taking care of the provincial rugby players and indeed the players at national level, but I think the HIA really needs to be looked at.
"If they are going to investigate all the protocols, then I think they need to look in the mirror. We know that concussed players can pass this HIA. George North, who described himself as ‘snake-dancing’ off the pitch, Brian O’Driscoll in the Autumn (2013) international against New Zealand (2013), he passed those tests, but my colleague Eanna Falvey didn’t allow him back on the pitch.
"I really am concerned about the HIAs," Beirne added: "I feel it is a very blunt instrument to assess a complex involved injury, in a very short time.
"This should be looked at independently by people who have no skin in the game, who are genuine experts."
