Glenavon travel to Ferney Park on Monday evening (kick-off 7.45pm) knowing a win will set up an Irish Cup quarter-final against either Glentoran or Armagh City.
The winners of this tie will travel to the winners of Monday’s replay at the Oval.
Gary Hamilton’s side have already won twice at Ballinamallard this season, David Rainey and Kyle Neill firing them to a 2-0 victory in September before Mark Patton earned a late victory last month.
Manager Gary Hamilton is hoping his squad can overcome fixture congestion to reach the quarter-final.
He said: “Our task would have been easier on a Saturday. Playing on a Monday after work makes it that bit more difficult. We won on a Tuesday night down there but that was with an extra day’s rest from the game on the Saturday.
“These are the type of games that can go either way. It’s only two games we’ve won down there. Last season, we didn’t beat them at all. There isn’t much between the two teams.
“At the minute, we’re probably playing with a bit more confidence than them but at the same time, it’s a cup game and if you don’t get the rub of the green, anything can happen.
“As we’ve seen with Ballymena beating Linfield, form counts for nothing.
“Hopefully we can give a good account of ourselves and get through.”
