Michael Bent could play in all three of Ireland's Tests after Declan Kidney described him as being "the most qualified in terms of being match-fit."
The New Zealander qualifies for Ireland through his maternal grandmother and has been training with the national side on Thursday and Friday.
He will then return to Leinster for their RaboDirect PRO12 clash with the Ospreys on Sunday, but is set to feature in the national side in November.
"It's our job to assemble the best Irish-qualified group together," head coach Kidney told reporters.
"In fairness to Leinster, they did a lot of groundwork in finding him.
"With the game-time the rest of the tighthead props have around the place, he's probably one of the most qualified in terms of being match-fit."
Bent, who recently played for Taranaki in the ITM Cup, played five times for the Hurricanes this year. Ireland team manager Michael Kearney added that his Test debut isn't far away.
"He could play in one or two or all three games in November. It depends on what happens in the next week or two," he said.
"Declan (Fitzpatrick) has just returned from injury, and we are keeping our options open."
