Also returning to the westerners' starting fifteen are Fionn Carr, Ian Keatley, Frank Murphy, Ronan Loughney, Robbie Morris, Mike McCarthy and Ray Ofisa.
Full-back Gavin Duffy and loosehead prop Brett Wilkinson are two notable absentees, with Duffy having injured his jaw in last week's loss to Munster and Wilkinson nursing a hand injury.
Jamie Hagan has recovered from a finger injury to feature again in the Connacht front row, while Troy Nathan will line out at full-back in a reshuffled back-line.
The surface of the pitch at the Sportsground has been covered in a bid to beat the big freeze and ensure that Saturday's eagerly awaited game goes ahead.
