Finlay Bealham will make his 100th Connacht appearance as they welcome Zebre to the Sportsground on Friday night (7.35ko).
He is one of four changes to the side which beat the Ospreys last weekend, with Darragh Leader and Gavin Thornbury both named in the starting XV.
Kieran Keane has also picked Sean O'Brien, with the number eight making his return to action after picking up a shoulder injury against the Southern Kings last September.
Keane also has a strong bench to call upon, with Kieran Marmion and Quinn Roux named among the replacements.
On bringing up his century for the province, Bealham said: “To be in that bracket of players that have reached the 100 appearance milestone is something I’m really honoured to be a part of.
“From my family’s perspective, they’re really proud. To walk out there for the hundredth time in front of a Sportsground crowd in the great atmosphere they always create is something I’m really looking forward to.”
Meanwhile Zebre coach Michael Bradley - who was in charge in Galway from 2003-2010 - has been able to name three of the Italian side beaten by Ireland in his starting XV, including outhalf Carlo Canna.
