Ulster coach Mark McCall has opted for Paddy Wallace ahead of David Humphreys at outhalf for his side's Celtic League clash with Edinburgh on Saturday.
Wallace, currently vying for the number 10 shirt at international level, relegates a former Ireland favourite to the bench ahead of the tour to Argentina in a fortnight's time.
Ulster are also without Bryn Cunningham who is suffering from a back injury. Tommy Bowe moves to fullback where he played as a schoolboy and Paul McKenzie starts on the right wing.
An injury to the foot of Ryan Caldwell means Tim Barker partners Justin Harrison in the secondrow. Lock Lewis Stevenson, who is leaving Ulster to play at Exeter next season, is named on the bench for the first time.
Ulster are currently fifth in the table, two points behind Llanelli Scarlets, who play Connacht tomorrow.
ULSTER: 15 Tommy Bowe; 14 Paul McKenzie, 13 Andrew Trimble, 12 Paul Steinmetz, 11 Andrew Maxwell; 10 Paddy Wallace, 9 Isaac Boss; 1 Bryan Young, 2 Rory Best, 3 Simon Best(captain), 4 Justin Harrison, 5 Tim Barker, 6 Stephen Ferris, 7 Neil Best; 8 Roger Wilson
