Ger Mahon replaces Shane Kennedy at full-back, Roderick Whyte comes in for Dermot Ryan at right half-back and Martin Nester takes over from Cyril Donnellan at left half-forward.
The team is notable for the inclusion of four of the Galway vocational team that defeated Tipperary in the All-Ireland final back in May Michael Donnellan, Niall Callanan, Donal Reilly and Niall Healy. Healy is an exceptional talent and will pose a lot of problems for the Tipp defence.
Mattie Murphy has taken over as coach of Galway. He was last involved in 1994 when Galway defeated Cork in the All-Ireland final. He says Tipperary will be hard to beat, having seen them in the Munster final against Cork, but adds his side are looking forward to the challenge. "We've had some tremendous games with Tipperary at minor level over the years and Sunday's should be no exception," said Murphy. "The recent All-Ireland vocational final was a tremendous contest and it was only in the last 10 minutes that Galway pulled away.
"There are a number of players from both teams involved on Sunday and again I'm expecting Tipperary to make it very hard for us. Antrim didn't pose too many problems for us in the quarter-final, but we played Cork in a challenge last week, which was very beneficial.
"We've made a number of changes in an effort to strengthen particular positions and hopefully, they'll work. With minors, you never know what to expect. It's a huge occasion for them, and it all depends on how they perform on the day."
Tipperary have made four changes from the team that defeated Cork in the Munster final. Brendan O'Sullivan and Brendan Hanley replace Ian Delaney and JB McCarthy in defence, while Shane O'Brien and Dara Hickey are preferred to James Woodlock and Damien Young in attack. O'Sullivan wasn't available for the Munster final because of a family bereavement while O'Brien did extremely when introduced against Cork and holds his place.
Coach Paddy McCormack said his charges are looking forward to playing in Croke Park: "It's where every young player wants to be. This will be our third meeting with Galway this season and understandably the most important.
"They'll be a big challenge for us. Along with Kilkenny they are favourites to win the All-Ireland, but I'm happy enough that if we play to our potential we'll beat them."
