Rob Kearney damaged ankle ligaments during the closing stages of that game, but the duo are being given every chance to prove their fitness ahead of the defending champions' crunch clash with Toulouse.
Fergus McFadden (calf) and Girvan Dempsey (neck) have also been included in the province's 27-man squad, despite picking up recent injuries.

Leo Cullen is one of 15 Ireland internationals named in the provisional panel for the Toulouse trip which also includes the likes of Shane Horgan, who has scored 26 tries in 77 Heineken Cup appearances.
Gordon D'Arcy, who has touched down on four occasions so far in this season's competition, is joined by Brian O'Driscoll's whose 28 career tries in Europe leaves him in third place in the record brooks.
Scotland's Nathan Hines and South Africa prop CJ van der Linde join Sexton, who has kicked 60 points so far in the campaign, in the extended squad. The starting team and replacements will be confirmed on Friday afternoon.
