Shamrock Rovers v Derry City, Tallaght Stadium, 7pm
Three behind leaders Dundalk with a game in hand, Shamrock Rovers know they can't take their foot off the gas in what already looks very much like a two-horse race.
It's two weeks since they beat Cork City 2-0 in Tallaght and they're on their own patch again for the clash with the Candystripes.
The visitors thumped Finn Harps last time out and will look to keep up the pressure on third-placed Bohs. A win for Derry would leave them a point behind the Gyspies.
Shamrock Rovers: Aaron McEneff is still out but Sean Kavanagh is expected to return. Dylan Watts has a knock and will be assessed.
Derry City: Darren Cole is doubtful. Patrick McClean nor Michael McCrudden are still unavailable.
Stephen Bradley (Shamrock Rovers): "They’ve shown this year already that they’re more than a match for anybody in the league. They’ll definitely come down to Tallaght and try to take three points. But we believe we’re ready, we’re focused to go and try and win the game."
Declan Devine (Derry City): "Rovers are a quality side and they’re a seriously tough nut to crack, especially at home, but these are the type of challenges we have to relish," he told the Derry Journal.
Sligo Rovers v St Pat's, the Showgrounds, 7.45pm
St Pat's could make it a hat-trick of wins against the Bit O'Red this season.
Sligo have been beaten on two occasions this year by the Saints, 1-0 and 2-1, so Liam Buckley will be desperate to get one back on his old club. Prior to the 4-0 loss at Dundalk they'd been in good form too, and go level on points with fifth-placed Pat's with a victory.
Sligo Rovers: Dante Leverock is away on international duty. Regan Donelon and Johnny Dunleavy are recovering from muscle injuries and making quicker progress than anticipated. Both will have pre-match fitness tests.
St Pat's: Conor Clifford is injured, while Jamie Lennon is on Republic of Ireland Under-21 duty at the Toulon Tournament. Former Sligo midfielder Rhys McCabe returns from suspension, and Lee Desmond will have a late fitness test.
Liam Buckley (Sligo Rovers): "It’s good to be back in The Showgrounds but it’s a hard game so we have to be at. I don’t think there has been much between the sides this year so we’ll give it our all and see where it takes us. We want to show the progress we feel we are making."
Cian Coleman (St Pat's): "Consistency is the key and that is what Harry [Kenny] has been telling us so if we can do that, we can win against Sligo and hopefully start to push up a few places in the table."
Finn Harps v Dundalk, Finn Park, 8pm
It doesn't get easier for bottom-of-the-table Ginn Harps who host the reignign champions and current table-toppers.
Ollie Horgan’s men face a massive task to get anything from the game but Harps will be hoping that they can repeat the performance that saw the two sides draw 1-1 at Finn Park at the end of February.
The Lilywhites have clicked into gear since then and come into this one on the back of an 11-match unbeaten run in the league - ten wins, one draw. They won't play for nearly three weeks after this game - the UCD clash postponed due to Ireland Under-21 call-ups - and are scheduled to head to Spain for a training break.
Finn Harps: Michael Gallagher, Harry Ascroft, Ciaran Gallagher and John Kavanagh are out while skipper Keith Cowan is a doubt. Mark Coyle returns from a one-match ban but Caolan McAleer and Sean Boyd are both suspended.
Dundalk: Robbie Benson [broken leg] and Jamie McGrath [foot] remain out but could both come back into the fold early next month, with Cameron Dummigan [ankle ligament damage] also on the comeback trail. .
Ollie Horgan (Finn Harps): "We have worked hard this week to be ready so it’s a case now of delivering the best performance possible tomorrow night. At the same time we’d hope that Dundalk are not at their best and a little bit of luck would be welcome as well."
Patrick Hoban (Dundalk): "They try to stop you playing, they sit in and they make it very difficult for you on the night," he told Dundalk Democrat. "But that’s down to us to go there and try our best to get three points. It’s never easy; you can see that if you’re not on your game, you get punished in this league. We have to make sure that we are on our game."
