Waterford footballers have made four changes to the side that fell to Clare in the opening round of the Munster SFC.
Richie Hennessy, Stephen Cunningham, Shane Walsh and Eamon Walsh all come into the side to face Louth in the All-Ireland qualifier in Drogheda on Saturday.
Hennessy has recovered from injury while Cunningham only returned from holidays on the morning of the match in Ennis.
Shane Walsh has completed his exams in Edinburgh and is now available to the Deise management.
Louth came out on top in the last clash between these sides, when they beat the hosts by two points, 1-11 to 1-9, in a league encounter in April in Dungarvan.
Waterford (SFC v Louth): T Wall, P Ogle, E Walsh, R Hennessy, A Heffernan, M Ahern, T Costelloe, A Hubbard, K O'Keeffe, S Cunningham, S Biggs, L Ó Lionain, N Curran, G Hurney, S Walsh.
