Mack Hansen has been recalled to Ireland's squad for next month's Nations Championship fixtures after almost a year of injury-enforced exile from international rugby union.
The 28-year-old Australia-born wing is one of three experienced players returning after lengthy lay-offs, with back-five forward Ryan Baird and loose-head prop Andrew Porter also included in a 36-strong group announced by coach Andy Farrell on Wednesday.
The trio last played for Ireland in the concluding game of last year's November series against South Africa at Dublin's Lansdowne Road.
Hansen required foot surgery, ruling him out for the rest of the season, but has since returned to action with provincial side Connacht.
Baird, 27, has recovered from a leg fracture while 30-year-old Porter was sidelined with calf problems.
Injuries among Ireland's loose forwards have led to a call-up for uncapped Ulster back-row James McNabney, while Jamison Gibson-Park has been included, even though the veteran scrum-half has yet to play for Leinster this season due to a groin strain.
Ireland captain Caelan Doris remains unavailable as he recovers from knee and foot injuries, with hooker Dan Sheehan skippering the side.
Ireland face Argentina, Fiji and world champions South Africa in Dublin next month ahead of a Nations Championship finals weekend at Twickenham.
Farrell's men have won two of their three Nations Championship matches so far, beating Australia and Japan before suffering a 40-21 loss to New Zealand at Auckland's Eden Park.
