Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
Ulster lock Ryan Caldwell is the player to lose out as Alan Quinlan and David Wallace stay in the matchday panel to bulk up the back row cover.
Wallace is fit to feature on the bench after recovering from a tooth abscess.
Explaining the decision to omit a specialist second row from the bench, Kidney said: "We just think, going into this game, there's going to be a lot of activity in and around the breakdown, so we've gone with a few extra loose forwards.
"We have enough cover in the second row, we feel we can slot them in if needs be.
"(If there is an injury in the second row) it will be a bit of mixing and matching between scrums and lineouts. We've been practising it during the week and feel we have enough cover there.
"It's a tough one on Ryan because he's been going well at training. We had to weigh up a number of minute factors and we just felt that this was the best combination (for the bench)."
