Connacht and Munster welcome back Irish internationals for the United Rugby Championship interprovincial showdown at MacHale Park on Saturday (14:30 GMT).
The hosts bring in Mack Hansen, Bundee Aki, Finlay Bealham and captain Cian Prendergast for what will be the first time a professional Connacht game is held in County Mayo, and the first time rugby is played at the Castlebar venue in its 95-year history.
The Ireland quartet are among seven Connacht changes from the 43-40 defeat by Ospreys in Wales.
Chay Mullins, Jordan Duggan and Sean Jansen also come into the starting XV.
Munster have three Irish internationals back in their side as Tadhg Beirne, Jack Crowley and Calvin Nash return.
The visitors are also boosted by the return of Oli Jager and Craig Casey from injury as they make five changes from the 28-25 defeat by Glasgow Warriors last weekend.
Munster sit sixth in the standings and three points above 12th-placed Connacht.
