Connacht head coach Pat Lam has been charged with misconduct by the Guinness PRO12 disciplinary officer.
It follows comments made by Lam to the media immediately after Connacht's 18-17 PRO12 defeat to Cardiff Blues last Friday.
Connacht were leading deep into stoppage time, but then conceded a converted try.
In a statement, PRO12 organisers said: "Pat Lam, the Connacht head coach, has been formally charged with misconduct by the disciplinary officer of PRO12 Rugby following comments he made to the media following the Guinness PRO12 match against Cardiff Blues in Cardiff on Friday evening, March 6.
"Pat Lam will be required to attend a disciplinary hearing, before an independent PRO12 Rugby disciplinary committee, at a date yet to be determined."
