In the pack; Nigel Brady switches places with Andy Kyriacou, from the bench to the starting line-up. Ryan Caldwell replaces an injured Dan Tuohy. Robbie Diack, who was not named on the original squad, starts at No8 with Willie Faloon as open side flanker. TJ Anderson is named as a replacement.
In the backs, the only change sees Andrew Trimble in for an injured Simon Danielli. Mark McCrea takes Trimble's place on the bench. Paddy Wallace will once again captain the side, pairing up with Darren Cave in the centre.
Ulster Lion Stephen Ferris will face his Lion's Tour teammate, on Friday night, as Stephen Jones returns for Scarlets in his first Magners League game of the season.
