Ireland star Bundee Aki will make his 100th appearance for Connacht on Sunday in the Guinness Pro14 clash against Ulster at the Aviva Stadium (live on RTÉ Radio 1, 4.30pm), with wingers Alex Wootton and Peter Sullivan set to make their debuts.
Aki joined Connacht in 2014 and has gone on to play a central role in the province's fortunes since then.
Wootton and Sullivan will both make their first appearances for the province after being handed starting berths on the wings.
They form a back three with John Porch, who slots in at full-back.
Tom Farrell will partner Aki in the centre, with Kieran Marmion and Jack Carty forming a formidable half-back partnership.
In the forwards, there’s a return to action for prop Finlay Bealham after he picked up a serious injury against Edinburgh in February. Bealham makes up an experienced front row with Denis Buckley and hooker Dave Heffernan.
Ultan Dillane and Gavin Thornbury have been named in the second row, and the starting XV is completed by flankers Eoghan Masterson and captain Jarrad Butler, with Paul Boyle named at number eight.
Three more players could make their Connacht debuts off the bench, with props Jordan Duggan and Jack Aungier, and back rower Conor Oliver all named as replacements.
Connacht coach Andy Friend is looking forwards to returning to action and said: "It has been almost six months since our last game and two months since we commenced pre-season training, so we are delighted our return has finally arrived.
"I have been really impressed with how the squad as a group have reacted to the uncertainty of the last few months, and it’s now our opportunity to show that hard work against an opposing team."
Connacht: Porch; Sullivan, Aki, T Farrell, Wootton; Carty, Marmion; Buckley, Heffernan, Bealham, Dillane, Thornbury; Masterson, Butler, Boyle.
Replacements: Murphy, Duggan, Aungier, Murray, Oliver, Kerins, Dean, Daly.
