Ireland's John Lacey will referee his first ever RBS 6 Nations match in February, while Alain Rolland is also included in the Elite Panel in what is his last season.
This failed to settle down before the Ireland training session on Thursday and following a scan yesterday afternoon it was confirmed that D'Arcy has a stress injury to a bone in his foot.
The injury will require immobilisation in a boot for at least four weeks with a projected return to play of six weeks pending further tests and specialist review.
The Ireland training squad for the Scotland test match week will be announced on Sunday evening following the completion of the RaboDirect PRO12 matches.
