Eadestown's Tadhg Beirne is one of the nine to start
Bundee Aki, Ollie Chessum and Andrew Porter will all start for the Lions in the second Test against Australia in Melbourne this weekend.
They come in for Sione Tuipoloto, Joe McCarthy - who has a foot injury - and Ellis Genge.
There are a record nine Irish starters for the tourists, and Garry Ringrose had been due to play before ruling himself out due to concussion.
Porter joins Dan Sheehan, Tadhg Furlong, Jack Conan and Eadestown's Tadhg Beirne in the pack.
Aki, Jamison Gibson-Park, James Lowe and Hugo Keenan all start in the backs.
