It is the first time Wilson has been named in a preliminary squad since his return to Ulster, having suffered a hamstring tear playing for Northampton Saints at the end of last season. The number 8 has enjoyed impressive outings for the Ravens in recent weeks and scored two tries in Sunday's loss to Bristol.
Fitzpatrick had suffered a reoccurrence of a medial ligament injury prior to the Connacht match earlier this month but has undertaken full training over the past week and will be hopeful of getting much needed game time.
Stephen Ferris has been included after missing the last two games with a back injury, while flyhalf Niall O'Connor has also been added to the panel.
Johann Muller has been ruled out for eight weeks after sustaining a thumb injury in Friday's Heineken Cup win over Glasgow. Ireland international back row Chris Henry will captain the side in Muller's absence.
Ulster continue to set the pace at the top of the PRO12 table, and still possess a 100% winning record in all competitions this season. The Ulstermen have won five of their last six fixtures with Welsh regions and have been victorious on their two visits to Wales so far this campaign.
Dragons' only win in their last seven matches in all competitions was 32-12 at home to Edinburgh in round five of the league. The Welsh outfit have an even worse record against Irish provinces, winning just one of their last 14 encounters. That success did come over Ulster though, just over 12 months ago when they registered a 22-9 win at Rodney Parade. The Ulstermen have managed only one victory at Rodney Parade since 2006.
