Jamie Mulgrew will miss Linfield's top two clash against Portadown at Shamrock Park because of a knee injury.
The in-form midfielder had to sit out last Saturday's win over Crusaders, which took the Blues three clear at the top, and is still not ready to return.
The Ports are currently three points behind the leaders, having won all four of their home games so far.
"They have started off well this season and they will be confident," said Linfield striker Peter Thompson.
"It is always difficult going there and, if we come away with a win, we will be delighted."
Shane McCabe is expected to come back into the Portadown team after serving a suspension.
Linfield, who have won four out of four away Premiership matches so far, will come up against their former player Jamie Tomelty who signed for the Ports at the end of last season.
"Jamie has been brilliant for us. He brings the experience of having won things at Linfield," said Portadown defender Chris Ramsey.
"He has been a breath of fresh air and we are glad to have them."
Tomelty was named Portadown's man of the match after their 2-1 win over Glentoran at Shamrock Park last Saturday.
That result sent the Glens slipping into the bottom half of the table.
Scott Young's side get a chance to improve on their disappointing home form when they take on Carrick Rangers at the Oval.
