Aki is set to face a disciplinary committee for comments he made to match officials last weekend.
Bundee Aki has been dropped from the Ireland squad ahead of next week's Six Nations opener away to France.
The Connacht centre is set to face a disciplinary committee for comments he made to match officials after Connacht's loss to Leinster on Saturday.
As a result, the IRFU has withdrawn the 35-year from their squad and he didn't travel with the rest of the squad for their training camp in Portugal.
The IRFU says it won't "tolerate any form of disrespect" shown towards match officials.
He's been replaced in the squad by Ulster's uncapped centre Jude Postlethwaite.
