Ireland and Ulster fly-half David Humphreys has been passed fit and will start in Saturday's Magners League opener against the Llanelli Scarlets at Ravenhill.
Humphreys had been struggling with a shoulder knock suffered during Ulster's 26-14 friendly win over Earth Titans last Friday.
Roger Wilson returns after suspension in place of Kieron Dawson as Ulster make only one change.
Welsh international fly-half Stephen Jones is also fit and will play opposite Humphreys but the Scarlets are without back-row pair Simon Easterby and James Bater.
Easterby, Bater and Jones were injured in the 29-22 loss at Gloucester, while Inoke Afeaki was sent off but the Tongan has been cleared to play as his two yellow cards were for technical offences and not foul play.
Wales and Lions scrum-half Dwayne Peel will lead the Scarlets as Easterby is missing.
Ulster: B Cunningham; M Bartholemeusz, P Steinmetz, P Wallace, A Maxwell; D Humphreys, K Campbell; J Fitzpatrick, P Shields, T Court, J Harrison (capt), T Barker, S Ferris, N McMillan, R Wilson.
Replacements: N Brady, D Fitzpatrick, M McCullough, K Dawson, P Marshall, K Maggs, S Young.
Scarlets: Martyn Thomas; Dafydd James, Regan King, Gavin Evans, Darren Daniel; Stephen Jones, Dwayne Peel (capt); Phil John, Matthew Rees, John Davies, Lou Reed, Scott Macleod, Inoke Afeaki, Gavin Thomas, Nathan Thomas.
Replacements: Craig Dunlea, Ken Owens, Adam Jones, Alix Popham, Clive Stuart-Smith, Ceiron Thomas, Matthew Watkins.
