Ireland have been forced into a late change for their autumn Test clash with Australia in Dublin, with Sean O'Brien ruled out through injury.
Josh Van der Flier will start at openside flanker, with Munster's Peter O'Mahony stepping up to the bench.
Ireland confirmed the change on Twitter, little more than an hour before kick-off at the Aviva Stadium.
Flanker O'Brien and centre Jared Payne were late injury doubts on Friday with what assistant coach Andy Farrell described as "lower-limb tweaks".
And now the influential Leinster star O'Brien has been forced out of Ireland's final autumn Test match.
