Swansea striker Danny Graham is set to miss Saturday's Premier League trip to Blackburn with an Achilles injury.
The former Watford player limped off during the second half of Swansea's goalless draw against Aston Villa last Sunday.
Boss Brendan Rodgers will wait before making a final decision, but says he is currently unlikely to feature.
"I would say it is more against than for [in terms of Graham's fitness]," he said.
"When Danny is injured you know he is properly injured as he is old school like that.
"I knew it was bad when he had to come off but we will assess it again tomorrow before we make a decision."
The 26-year-old joined Swansea for a record £3.5m from Watford in June and has scored four goals in the Premier League this year.
Another Swansea summer signing, Leroy Lita, is likely to face the Premier League's bottom side should Graham fail to recover from his injury.
And Rodgers says the former Reading and Middlesbrough forward is a more than able deputy for Graham.
"Leroy is very hungry. He has been fantastic and he is a great professional, and that's not easy as a striker as you live for goals and games," added Rodgers.
"He has been a great squad player and he has to keep working, and when the chance comes he has to take it.
"When he came on last week he was strong and aggressive and he can give defenders problems.
"If Danny is not ready and I need to use Leroy I will have no doubts. That's why I brought him here."
Swansea will also be without defender Angel Rangel for Saturday's trip to Blackburn.
The Spaniard is likely to be sidelined for up to a month and Wales Under-21 captain Jazz Richards is set for a first Premier League start.
"It's a blow to lose Angel as he has been a regular since I have been here," said Rodgers.
"He has grown so much in the last three or four seasons and he has coped very well with the Premier League.
"But we have young Jazz Richards, who has been waiting for an opportunity.
"He showed when he came on last week that he is a strong defender and is not easily beaten so I have every hope he can come in and do an excellent job."
