There is a pivotal feel to today's Leinster round-robin encounter at Parnell Park.
Defeat for hosts Dublin at Donnycarney and it seems highly improbable that Mattie Kenny’s first year in charge will extend beyond the provincial games.
A home victory however would really open things up and put added pressure on Wexford’s trip to Salthill the following weekend.
The fixture list has thrown up the oddity that the Yellowbellies are without a home game until round four and manager Davy Fitzgerald knows that the disappointment of Dublin's defeat to Kilkenny, coupled with their enviable home record, makes it a difficult opening assignment.
We know what’s coming down the tracks
"Sunday is a big test," he told RTÉ Sport. "We know Dublin are going to bring everything to it. They put up a good performance against Kilkenny, but they need to win this one.
"We know what’s coming down the tracks.
"Parnell Park is a fortress to Dublin, but we realise that and we know the challenge that is coming. We have got to meet it head on, but we’re looking forward to it."
Paul Morris has been ruled out, but forward Conor MacDonald is expected to feature as Wexford will be aiming to lower Dublin colours for the second year running
"As we saw last week with the championships, anything can happened. I’m excited. Let’s see what happens."
