Meath play Dublin in the other last four contest.
Westmeath were first to name their team for this massive Leinster U-20 Football Championship semi-final.
Damien Gavin's side have already secured victories over Kildare and an epic penalty shootout win over Longford last week following a final score of 2-12 to 3-9.

In all, the high scoring lake county have hit 3-27 in the championship thus far and will be hoping their potent forward line will do the business again.
Eight clubs are once again represented in the starting team, Coralstown-Kinnegad, St.Lomans, Athlone, Ballinagore, The Downs, Milltown, Milltownpass and Killucan.
Gavin makes one change between the pipes as Sam Martin takes over from Michael Lynam of St. Josephs.
Westmeath starting XV:
Sam Martin; Josh Gahan, Charlie Drumm, Ciaran Daly; Enda Gaffney, Darragh Seery, Michael Byrne, Jack Murtagh, Ciaran Daly; Shane Fleming, Kevin O'Sullivan, Brandon Kelly; Jack Torpey, Ben McGauran, Devin Hill.
Meanwhile Declan Kelly has stuck with the same Offaly team that defeated Wexford by a solitary point last Thursday in Wexford Park.
Ten clubs have sent players to this starting team, Shamrocks, Bracknagh, Edenderry, Tullamore, Shannonbridge, Clara, Ferbane, Rhode, Ballinagar and Kilcormac-Killoughey.
Offaly starting XV:
Sean O'Toole; Fionn Dempsey, Kieran Dolan, Lee Pearson; Rory Egan, John Furlong, Aaron Brazil; Ed Cullen, Morgan Tynan; Ciaran Egan, Cathal Flynn, Cathal Donoghue; Cormac Delaney, Jack Bryant, Aaron Kellaghan.
Offaly's starting 15 for the @gaaleinster U20 Football Championship v Westmeath tomorrow (Thursday) evening is the same as started v Wexford.
