Will Addison could be handed his first start for Ireland today.
The Ulster player is being tipped to be named at full back for Saturday's November Test against Argentina at Lansdowne Road.
Rob Kearney looks set to be ruled out due to shoulder injury, but Jordan Larmour and Andrew Conway are also in the running for the number 15 shirt.
Addison came off the bench to make his international debut against Italy in Chicago at the weekend.
Schmidt is expected to name a much changed team with Rory Best and Sean O'Brien among those recalled.
The Ireland captain missed the summer tour to Australian, while O'Brien hasn't played for the international side in almost a year.
Kieran Marmion looks set to join Johnny Sexton in the half backs.
