Ulster boss Mark McCall has named a 23-man squad for the game against Glasgow on Saturday, 6 January, kick-off 5.30pm.
Adam Larkin is brought in as cover for the injured David Humphreys who is not included in the squad as he hurt his left arm in the first few minutes of Sunday's game against Leinster at Lansdowne Road.
An MRI scan has revealed a degree of bony bruising from the impact and significant soft tissue damage.
However, with intensive treatment and rehabilitation there is an outside chance Humphreys could be fit for the away Magners League trip to the Ospreys at the end of January.
McCall's men will be hoping for a win to extend the lead at the top of the Magners League table. Glasgow are currently on a good run having won six of their last nine games.
McCall will name a team on Friday at 12.00noon.
BACKS: Kieran Campbell; Isaac Boss; Adam Larkin; Paddy Wallace; Kevin Maggs; Paul Steinmetz; Andrew Trimble: Paul McKenzie; Mark Bartholomeusz; Bryn Cunningham; Tommy Bowe.
FORWARDS: Simon Best (Captain); Bryan Young; Justin Fitzpatrick; Rory Best; Paul Shields; Justin Harrison; Matt McCullough; Tim Barker; Roger Wilson; Neil Best; Kieron Dawson; Neil McMillan.
