The Irish arrived in Auckland minus the pair late on Sunday night and team manager Paul McNaughton said even if the outcome was favourable for both players neither would be considered for Saturday's Test against New Zealand in New Plymouth.
Flannery has yet to have a scan on the calf he injured in the loss to the Barbarians on Friday.
"Jerry is getting a scan on Tuesday morning when the injury settles down and depending on the results of that scan he may join us," McNaughton said.
"If the scan is clear he'll be with us and he will travel on Tuesday but he won't be in consideration for this game."
Horgan is still undergoing tests for the stomach complaint which forced him to withdraw from the match at Thomond Park.
"Shane Horgan is just continuing with some tests and again we'll make a call on bringing him out on Tuesday or Wednesday at the latest and again he won't be considered for the All Blacks game."
There was better news regarding fly-half Jonathan Sexton, who has recovered from the infection in his gum close to where he had recent surgery on his jaw, and will be available for selection for the New Plymouth showdown.
Injuries have certainly robbed Ireland of some of their best talent for the three-match Australasian trip, which also includes a match against New Zealand Maori and a Test against Australia in Brisbane.
The absent include British and Irish Lions skipper Paul O'Connell, Rory Best, Keith Earls, Kevin McLaughlin, Fergus McFadden, Luke Fitzgerald and Denis Leamy.
