Peter Russell, who had a few outings with the county senior hurling team, is named at centre-forward.
Waterford make one change from the team that defeated Tipperary. Defender Patrick Lynch received a straight red card and De La Salle's Killian McBride comes in at left half-back, with Mark Prendergast of Kilrossanty switching to the flank to fill in for Lynch.
Waterford will be attempting to reach their third provincial final in three years and their third in half a decade.
They lifted the title for an historic first time in 2003 with a famous victory over Kerry at Walsh Park (having defeated Cork in the semi-final), and the sole survivor of that history-making team is centre-back David Hickey.
Three members of the Waterford senior team crushed by Cavan in the National League last Sunday Kieran Connery, Liam O'Lionain and Patrick Hurney are also named in the side, at left full-back, right half-forward, and full-forward respectively.
