Jason Harris-Wright suffered a calf muscle strain during last weekend's interprovincial clash at Musgrave Park and is out of action this week as a result. Adrian Flavin is named at Hooker for tomorrow's fixture, earning his 140th cap for Connacht.
Ronan Loughney comes into the front row in place of Nathan White who moves to the bench.
The second row is made up of Mick Kearney and Ireland international Mike McCarthy, who returns to the starting XV this weekend.
There's a reshuffle in the back row with John Muldoon returning to his more familiar Blindside Flanker position. Willie Faloon, who picked up a slight ankle injury this week in training, is replaced by Galway-born Eoin McKeon at number 7. George Naoupu starts at Number 8.
On the bench, Dave Heffernan is named amongst the forwards' replacements. The 22-year-old, Ballina-man who recently signed a development contract that sees him progress to the senior squad next season, earned his first senior cap against Scarlets this time last year.
