The news will come as a further boost to coach Mark Anscombe, following his side's 18-10 win over Glasgow on the opening weekend.
Rory Best and Chris Henry are still unavailable because of the IRFU's player management scheme but are expected to make a return in the coming weeks. Roger Wilson (hamstring) and Paddy Wallace (shoulder) will make a come back in October, but Adam D'Arcy and Ali Birch should be available in the next week or two. Nevin Spence has returned to full training after injury but will not be considered for this weekend.
