Prop Cian Healy is expected to miss the start of the 2014 RBS 6 Nations after undergoing surgery on his injured ankle on Wednesday.
BJ Botha and Stephen Ferris continue their rehab from elbow and knee injuries respectively, but on a more positive note, Dan Tuohy is included in the extended squad as he looks to return from a quad tear.
Ulster's game against the Newport Gwent Dragons was originally due to be played at the beginning of December but fell victim to the wintry conditions. Tickets issued for the December match are valid for Friday night's fixture.
Ulster currently occupy fifth place in the Magners League table with ambitions of making a play-off place. Tickets are available to purchase from www.ulsterrugby.com.
Ulster Rugby would advise supporters coming to the game (gates open 5.30pm) to avoid parking in the immediate vicinity of the Ravenhill grounds where restrictions may be in place, and instead make use of the Park 'n' Ride facilities at Pirrie Park and along Montgomery Road.
Meanwhile, Tommy Seymour, who is part of the Ulster squad to face the Dragons, is set to play for Glasgow Warriors next season. He has signed a two-year deal with the Scottish club.
