Glasgow Warriors scrum-half Niko Matawalu and Munster counterpart Conor Murray have been cited after
Friday's win by the Irish side at Scotstoun.
Matawalu is accused of biting lock Donncha O'Callaghan, while Murray allegedly struck Matawalu.
The Rabodirect Pro12 has announced that a hearing will be held before an independent RaboDirect PRO12 disciplinary committee.
A date for the hearing has yet to be announced.
Glasgow Warriors statement
“We believe a dangerous act of foul play was committed by a Munster player against Niko Matawalu”
Both incidents had been highlighted by Rob Flockhart, the Scottish citing commissioner after reviewing video footage of the match, after which Warriors coach Gregor Townsend acknowledged the robust Munster defence.
The league stated that Matawalu "has been cited for foul play contrary to law 10.4 (m) - act contrary to good sportmanship (biting)", while Murray "was also cited for foul play contrary to law 10.4 (a) - striking with the elbow".
A Warriors spokesman had said after the match: "We believe a dangerous act of foul play was committed by a Munster player against Niko Matawalu.
"We have formally written to the citing commissioner to draw his attention to this.
"The matter is now with the citing commissioner and Celtic Rugby to review as part of their disciplinary process.
"Glasgow Warriors will be making no further comment whilst the matter is being investigated by Celtic Rugby."
If found guilty at Wednesday's hearing,
Murray could be banned for eight weeks, ruling him out of Ireland's Tests with Samoa, Australia and New Zealand.
Matawalu was a replacement for Chris Cusiter for the Celtic League meeting, but the Fijian has been first choice for Glasgow's Heineken Cup campaign.
Munster leapfrogged Glasgow to the top of the Pro12 following their 13-6 win in Scotland.
