Ospreys captain Justin Tipuric has been cited for a dangerous tackle during his side's 13-17 Pro12 win over Munster at Thomond Park on Sunday.
Flanker Tipuric was penalised for a spear tackle on Munster fly-half Ian Keatley during the second half.
Munster prop BJ Botha has also been cited by an independent commissioner for striking one of the Ospreys players.
Tipuric faces a disciplinary panel on Tuesday, 18 October in Edinburgh.
The hearing's timing and outcome could deny Tipuric the chance to be called up by Wales as cover for banned skipper Sam Warburton for their third-place World Cup play-off against Australia on Friday, 21 October.
