Waterford FC are asking those attending the CorkCity game at the RSC on Friday night to pre-purchase their tickets.
The game is expected to sell out. There are three thousand seats with some limited standing room available.
The club say tickets are available online and in the club shop this evening and tomorrow evening from 5 to 7.30pm.
It's the first of two visits by the Leesiders who will return on Monday for the rescheduled EA Sports Cup clash.
A win for the homeside at the RSC on Friday night would leapfrog the Blues over Cork into top position in the Premier Division.
Kick off is at 7.45pm.
Matt Keane will have updates from the match on WLR.
