Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
"We must keep the ball in hand and play some strong and smart running rugby.
"If we are going to come away with the win we really need, we'll have to play out of our socks and be mentally prepared for a real fight.
"We were very disappointed with our performance last Friday, so it is great to have this early opportunity to play Cardiff again.
"We have had plenty to work on from last week and have been in Jordanstown for the past two days which has been great.
"We must make sure that we make our home advantage count, and get our Ravenhill support behind us to get as much out of this game as we possibly can."
Paddy McAllister and Tommy Seymour are additions to the squad that was selected for the Cardiff away game last weekend, while Tom Court and Mark McCrea were not considered due to injury.
Other players currently sidelined by injury are: Clinton Schifcofske, Willie Faloon, Bryn Cunningham, Adam Macklin, Ian Porter, Cillian Willis, Matt McCullough and Justin Fitzpatrick.
