Irish Premiership: McFall bullish for Glens showdown
Portadown manager Ronnie McFall is confident his team can leapfrog Glentoran into fourth place in the Premiership with a win at the Oval.
Glentoran lie two points above the Ports ahead of Saturday's clash.
"We'll go there positive, looking to win. It's a ground we always do well at - it doesn't hold any fear for us whatsoever," said McFall.
The Glens are missing Aaron Boyd and Richard Clarke while Ports striker Gary Twigg (groin) is rated doubtful.
Tim Mouncey and Shane O'Connor are also concerns for Portadown because of knee injuries.
Boyd is suspended after his dismissal against Dungannon Swifts on Wednesday while Clarke is attending a wedding.
"It's going to be a tough game. We need a win to stay on the coattails of those above us and put a bit of daylight between ourselves and Portadown," said Glens boss Eddie Patterson.
The sides will meet again in the Irish Cup a week later and Glentoran's new signing Curtis Allen is expected to make his debut for the holders at Shamrock Park.
Leaders Linfield face a trip to an improving Warrenpoint side, which has won four of their last five games.
The Blues are boosted by the return of Michael Gault from suspension while Town welcome back Darren King and Jonathan Parr for the Milltown game.
Coleraine will attempt to halt a run of nine straight league defeats when they take on bottom side Ards at the Showgrounds.
Former Derry City striker David McDaid is in line to make his Bannsiders debut while Ards will be without Ben Roy, as the forward has joined Championship side Carrick Rangers.
Another player set to move on is Ballymena striker Shane Dolan, who wants to leave the club due to personal reasons.
Sky Blues defender Mark McCullagh (hamstring) is doubtful for the Showgrounds game against Ballinamallard, who hope to give Liam Martin his debut after signing from Sligo Rovers.
