Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
Included in the squad for the first time is Scottish international Rob Dewey who was part of the Scottish squad that reached the World Cup quarter-finals. Dewey signed for Ulster from Edinburgh in February on a two-year contract.
David Humphreys is named in the squad after recovering from his ankle injury that sidelined him for the last number of weeks. Humphreys proved his fitness by playing for the Ulster "A" side against Leinster last Friday.
Also returning is lock Ryan Caldwell who has completed his three-match suspension following his red card against Edinburgh last month.
Back from World Cup duty is centre/winger Andrew Trimble. The Coleraine man is looking forward to playing for his province again and lining out against his Ireland team-mates.
Trimble said: "It will be great to run out at Ravenhill again and be back playing for Ulster against Leinster, our Interpro rivals. Playing against another province certainly adds an extra edge to a game.
"All the Irish guys know each other really well but I guess those friendships will have to be put to one side on Friday night. It is important that we get a good result in this game and get our Magners League campaign back on track."
Friday's encounter has been designated as an all-ticket affair with no tickets available at the gate on match night.
Tickets are available online from www.UlsterRugby.com and the Ulster Rugby ticket line (tel: 028 9049 3222 (Option 2)) or alternatively from over the Ravenhill counter.
