Darren Cave and captain Johann Muller return to the Ulster squad for the RaboDirect Pro 12 clash against Treviso on Saturday.
Cave has recovered from a foot injury and last featured over two months ago in the Heineken Cup win over Leicester.
Muller's previous game was a week earlier against Clermont Auvergne, before he suffered a calf injury in training.
The province will be without rested internationals Rory Best, Andrew Trimble and Stephen Ferris after the trio featured heavily for Ireland in the 6 Nations.
Ulster squad:
Forwards: C Black, T Court, A Macklin, J Afoa, J Cronin, P McAllister, A Kyriacou, N Brady, L Stevenson, Dan Tuohy, J Muller (captain), I Henderson, T Barker, N McComb, W Faloon, P Wannenburg, A Birch, C Henry, R Diack
Backs: P Marshall, R Pienaar, I Porter, I Humphreys, L Marshall, I Whitten, N Spence, D Cave, S Terblanche, C Gilroy, C Gaston, C Cochrane, A D'Arcy
Simon Danielli is still struggling with injury and is not fit enough to be named, while Mike McComish is unavailable after suffering concussion during the Edinburgh match earlier this month. Jared Payne and Declan Fitzpatrick also remain sidelined.
There is also a place in the extended squad for Phoenix Academy second row Iain Henderson, who was a key player in the Ireland U20s squad in their 6 Nations campaign.
