Andrew Trimble and Paddy Wallace are back from Ireland duties, ahead of Ulster's crucial away Magners League fixture against Scarlets on Friday night.
Ulster currently sit in sixth place in the league table on 25 points with Scarlets in ninth place on 17 points.
Ulster Coach Brian McLaughlin has named a 27-man squad ahead of the game.
"We have to go to the Scarlets really positive about our own ability to win away from home," McLaughlin said.
"We have to go to Llanelli and be accurate with everything we do. It is going to be very, very tough, they have an experienced squad and we'll have to be clinical with the chances we create and come away with the right result."
The backline is bolstered with the return of Trimble and Wallace, while Nevin Spence is also included in the squad, following his return from the Ireland Under 20 camp.
The team will be announced on Thursday.
Ulster squad forwards:
Tom Court, Bryan Young, B.J Botha, Declan Fitzpatrick, Nigel Brady, Andy Kyriacou, Ryan Caldwell, Ed O'Donoghue, Dan Tuohy, Thomas Anderson, David Pollock, Willie Faloon, Chris Henry, Robbie Diack.
Ulster squad backs:
Cillian Willis, Isaac Boss, Paul Marshall, Ian Humphreys, Niall O'Connor, Paddy Wallace, Darren Cave, Ian Whitten, Timoci Nagusa, Andrew Trimble, Simon Danielli, Jamie Smith, Nevin Spence.
