Connacht flanker Eoghan Masterson will earn his 100th cap for the province when they host Ulster in the Guinness PRO14 tomorrow evening.
He's been named in a back-row with Conor Oliver and captain Jarrad Butler as Andy Friend makes six changes from last week's loss to Bristol.
Shane Delahunt, Quinn Roux, Caolin Blade, Tom Daly and Tiernan O'Halloran join Butler in coming into the starting 15 for the Westerners.
Ian Madigan has been named at out-half for Ulster, where he'll join Alby Mathewson in the half-backs for the game at the Sportsground.
Dan McFarland has handed first seasonal starts to props Kyle McCall and Tom O'Toole.
Kieran Treadwell returns in the second-row while Greg Jones comes in to start at blindside flanker.
Ireland internationals Billy Burns, Rob Herring and Jacob Stockdale have all been rested as part of the player management programme.
