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.

England Under-20s head coach Martin Haag was full of praise for his World Rugby Under-20 Championship-winning side after Harry Mallinder inspired them to a 45-21 win over their Irish counterparts and a third title in four years.
