Swansea defender Kyle Naughton has been ruled out for the rest of the season with ankle ligament damage.
Naughton was hurt during Swansea's 3-1 Barclays Premier League home victory over Hull on Saturday in a challenge which saw Tigers midfielder David Meyler shown a straight red card.
A statement on the official Swansea website said a second scan confirmed ligament damage that will keep the January signing from Spurs out for around six weeks.
The 26-year-old has made nine Premier League appearances for the club since the switch.
Meanwhile Dejan Lovren will make his first Liverpool start in tonight's FA Cup replay since the original tie against Blackburn Rovers at Anfield over a month ago.
Striker Mario Balotelli, who missed Saturday's league defeat at Arsenal with a knee problem, will be assessed ahead of the short trip to East Lancashire.
Manager Brendan Rodgers has revealed that despite being assessed by the club's medical team prior to the weekend's defeat to Arsenal, the player was uncomfortable travelling to the Emirates with the knock.
