Danny Graham is prepared to push himself through the pain barrier in order to face Blackburn, but Swansea will be without Angel Rangel.
The Swans will travel to Ewood Park on Saturday looking to push themselves into the top half of the Premier League table and dump rock-bottom Rovers deeper into the mire.
They will hope to make the trip with Graham at their disposal, with their summer signing from Watford having started to settle among the top flight elite.
He is, however, nursing an Achilles injury picked up in Sunday's 0-0 draw with Aston Villa and faces a race against time to prove his fitness.
"It's still sore but it's a lot better than it was yesterday," Graham told the Swans' official website on Wednesday.
"I've got to take each day as it comes.
"Injuries are part and parcel of the game, but I've been fairly fortunate with them so far in my career.
"I'm still hopeful of making Saturday, but I think the next 24 hours will be crucial once the swelling has gone down.
"Although it's still early in the season, Saturday's game is massive. If we can pick up a win at Ewood Park it will move us 10 points above Blackburn, which will be a good cushion to have going into the busy Christmas and New Year period.
"It's a game I want to be fit for."
While Graham is hoping to face Blackburn, Rangel will play no part in the crunch clash.
The Spaniard is facing up to four weeks on the sidelines after falling awkwardly during the weekend stalemate with Villa.
"He had to leave the stadium on crutches and a scan on Tuesday confirmed the right-back has damaged his ankle ligament, meaning he could be sidelined for up to a month," read a statement released by the club.
"The 29-year-old is expected to miss a number of the Swans' festive fixtures, starting with Saturday's trip to Blackburn, though Brendan Rodgers has cover in Brynmelyn product (Jazz) Richards."
