AIL DIVISION THREE
Table-topping Ballynahinch are hoping to have centre Stuart Megaw and flanker Willie Faloon fit as they host Sunday's Well.
Hinch have won all four games picking up three bonus points and player/coach Daniel Soper is happy with the start to the season.
"We were happy to go away to Old Wesley and get a bonus point. We didn't play well in the first half but played good rugby in the second half," he said.
"We hope to string 80 minutes together and if we perform well the results will come.
"We'll keep taking each game as it comes and it is important that we maintain our cushion."
Although the Munster side have only one win, Soper isn't taking anything for granted.
"They will be a very tough and physical side and we'll have to get stuck in up front," he added. "There is not much difference between top and bottom in the league, we'll need to be smart and keep the ball."
Winger Kyle Corrigan is a fitness doubt.
Second placed Instonians travel to bottom of the table Portadown hoping to repeat last week's cup victory. Coach Clem Boyd has a full strength squad to pick from as Inst look to keep the pressure on Hinch.
Queen's host Old Wesley at the Dub hoping to maintain their excellent from which has yielded three wins in their last three games. The students are boosted by the return of scrum half Michael Pyper, centre Ian Whitten and winger Michael Barker.
Oliver Goss continues at out half while prop Michael Ferguson is hamstrung.
Ards face a tricky trip to Nenagh as they look for they third consecutive league win.
The Hamilton Park side have injury doubts over hooker Ryan Fisher, prop Tenari Fagimila, loose forward Ken Heaslip and centre Peter Glass.
Rainey will wait to name their starting line up for the trip to Waterpark as there are a few niggling injuries in the squad.
Kiwi centre Darryl Porter is definitely ruled out. Second row Connor Laverty faces a fitness test and back rower Simon McKinstry could also miss out.
Evan Stewart is set to make his AIL debut if McKinstry isn't passed fit in a back row that includes player coach John Andrews. Owen McMurray returns to the centre with James McBride and Gavin Martin on the wing. Michael Glancy continues at outhalf.
Banbridge and City of Derry clash at Rifle Park. Derry will be hoping for their first win of the campaign while the Bann men need the points to keep their hopes of a top four alive.
