Hooker Mike Sherry left the Dublin 4 ground on crutches but merely as a precaution after he twisted an ankle during the course of the game.
The pair are expected to be fit to face the French side on Saturday along with prop Marcus Horan who should be in contention after recovering from an eye injury.
A decision on Niall Ronan's fitness will be made after it is seen how he comes through training this week - the flanker has been nursing a groin injury.

He added: "So again, I don't think next week defines our season. I think there's a lot of footy to go. I think our ability to produce good performances on a consistent basis, and when we've got a foot on the throat, to be able to nail the opportunities that are presented to us is not happening at the moment.
"To say that next week defines our season, or the next two weeks even defines our season I think is a bit harsh, a bit short-sighted, given that we've some lads that are new to this.
"Any real opportunity for them to play is a growing opportunity. And I, for one, am really positive about the direction that they are headed."
