However, full-back Gavin Duffy and prop Brett Wilkinson will be notable absentees as Connacht look to repeat their heroic win over Leinster from last season.
Michael Bradley's men put in a super-charged display to run out 19-18 winners in a memorable match at the Sportsground in October 2008.
But, unfortunately, Duffy injured his jaw in the recent 35-3 loss to Munster and Wilkinson also picked up a hand injury in that game, so the Connacht management are planning without two of their key players.
Saturday's interprovincial encounter with Leinster will be the first of three home games for Connacht in the space of the fortnight.
The Newport Gwent Dragons will visit in the Magners League on Friday week, with Montpellier arriving for a crucial Amlin Challenge Cup clash a week later.
Connacht officials are expecting a big crowd for this weekend's interpro. Tickets can be purchased here.
