Andrew Browne, making way for Johnny O'Connor, moves from flanker to lock position and partners Mick Kearney in the second row.
There are no changes to the back line while, on the bench, there are a few new faces. Prop JP Cooney is named among the front row replacements. Garryowen's Bateman Cup winning prop joined the club last summer and has made a notable impression for the Connacht Eagles in the British & Irish Cup.
Athlone-born Danny Qualter is also named on the bench. The 20-year-old is in his third year of the Connacht Academy and could earn his first competitive start at the Sportsground tomorrow afternoon.
Following a lengthy injury spell this season, scrum-half Paul O'Donohoe returns to the fray a week ahead of the Heineken Cup Round 3 game with Biarritz.
Connacht's last six RaboDirect PRO12 fixtures have all been won by the home side on the day and the men in green will be looking to repeat last year's win (26-13) over Michael Bradley's side to earn their third home win of the season.
