Striker Nicky Forster is out of Friday's live Sky game at QPR. The former Reading man was replaced in the first half of last night's Carling Cup defeat at Peterborough with a groin problem.
Town's head of sports science Dave Williams told the club site: "Fozzie has a small tear in his abductor muscle and will definitely miss the QPR game.
"The injury is likely to keep him out for around two weeks, so it's touch and go for the Southampton match as well."
