Paddy Jackson, who scored his first try for Ireland last Saturday, has been released from international duty and will start for Ulster against Scarlets at Ravenhill tomorrow night (7.05).

The young outhalf’s inclusion is one of four personnel and three positional changes to the side that defeated Ospreys at Ravenhill last weekend.

Jared Payne moves from outside centre to fullback with Darren Cave reverting to his more familiar role at 13. Craig Gilroy continues on the right wing with Michael Allen keeping his place on the left.

Luke Marshall starts at inside centre alongside Cave, with Jackson at outhalf and Ruan Pienaar, who played his 75th game for Ulster against Ospreys, named at scrumhalf.

There are no changes to the front row, where Tom Court, Rob Herring and John Afoa all start. Johann Muller captains the side from the second-row with Iain Henderson selected alongside him.

Roger Wilson moves across the backrow to blindside, with Sean Doyle continuing at openside and Nick Williams coming in at number eight. Robbie Diack and Ricky Andrew, who both started last week, are named among the replacements.

Ulster have lost just once at Ravenhill in the past 12 months, however, Scarlets beat Ulster at Parc y Scarlets earlier in the season.
