Swansea boss Brendan Rodgers concedes £3.5m striker Danny Graham is unlikely to be fit for Saturday's Premier League trip to Blackburn.
Graham will be given until the last possible moment to recover from an Achilles injury sustained in Sunday's goalless draw with Aston Villa.
The striker, who has netted four top-flight goals since his summer move from Watford, has admitted he will play through the pain barrier to lead the Swans line against Rovers.
But Rodgers believes the odds are stacked against his top scorer.
The Northern Irishman said: "I would say [Graham being fit] is more against than for.
"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."
Former England Under 21 striker Leroy Lita is likely to get the nod if Graham misses out.
Rodgers is already without right-back Angel Rangel, who suffered an ankle injury against Villa and is set to be sidelined for up to a month.
Wales Under 21 captain Jazz Richards is set to deputise at Ewood Park in his first Premier League start.
Rodgers added: "Young Jazz Richards 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.
"I have every hope he can come in and do an excellent job."
