Not his best moment.

A 'Misconduct Complaint' against the 35-year-old was after comments made to match officials at the match.

In a statement, the IRFU said: "The IRFU can confirm that Bundee Aki has not travelled with the Men’s senior squad to Portugal for disciplinary reasons.

"The IRFU does not tolerate any form of disrespect shown towards match officials and does not condone actions that fall below the standards expected of players representing Irish rugby.

"The IRFU are investigating the matter further internally and no additional comment will be made at this time.

"Aki has been replaced in the squad by Ulster’s uncapped centre Jude Postlethwaite.

"Meanwhile, Hugo Keenan will return to Ireland tomorrow after sustaining a fractured thumb in training on Tuesday afternoon in Portugal."

Below are two incidences during the game where referee Eoghan Cross took umbrage to Aki' actions, and even gave a penalty against him for screaming in his face.

A statement from the URC implies that they are taking action due to comments from Aki towards match officials that were made after the game.

It reads: "Connacht Rugby’s Bundee Aki will appear in front of an Independent Disciplinary Committee in relation to a Misconduct Complaint made against him under the URC Disciplinary Rules.

"After the Round 10 BKT United Rugby Championship fixture on Saturday, January 24 at Dexcom Stadium, Galway, the Player is alleged to have engaged with the match official team on several occasions in a manner which may be deemed to be in breach of the league’s Disciplinary Rules related to Misconduct (including Clause 3.1, 3.2 and 3.3).

"An Independent Disciplinary Committee will meet today (Wednesday, January 28) to consider the Complaint in accordance with the URC Disciplinary Rules. Roddy Dunlop KC (Scotland) will serve as Chair, with Attie Heyns (South Africa) and Andrea Caranci (Italy) completing the committee."
