Wallabies forward Dean Mumm's act of striking an All Blacks player merited a red card, the citing commissioner said.

Wallabies flanker Dean Mumm has been cited for alleged foul play after All Blacks lock Brodie Retallick was flattened in the second half of the third Bledisloe Cup rugby test.

Mumm appeared to strike Retallick with his left elbow in the 52nd minute after the All Blacks giant tried to pull him away from a ruck during the match at Auckland's Eden Park.

Retallick hit the deck and stayed down, and will have to pass concussion protocols to be considered for the All Blacks tour opener against Ireland in Chicago on Sunday week. Wellington utility Vaea Fifita has been placed on standby in case Retallick doesn't receive clearance.

Mumm is alleged to have contravened Law 10.4 (a) A player must not strike an opponent with the fist or arm, including the elbow, shoulder, head or knee(s).

Referee Nigel Owens did not see the incident.

Upon further review of the match footage, the citing commissioner deemed the incident had met the red card threshold for foul play.



The citing is to be considered in the first instance by duty judicial officer (DJO) Robert Stelzner SC.



For a matter to be dispensed with at this DJO hearing, the player must plead guilty and accept the penalty offered by the DJO.
