The severity of Watford defender Fitz Hall's hamstring injury will be assessed today.
Hall missed last night's 0-0 draw with Millwall due the problem and speaking after the game, head coach Gianfranco Zola said: "The injury shouldn't be too bad but we are not too sure whether he will be out for one week or two weeks. We will have a proper assessment tomorrow."
Hall's injury meant a full debut for Swedish defender Joel Ekstrand, who had previously only made two substitute appearances for the Hornets since his arrival on loan from Udinese.
Zola said: "Ekstrand debut pleased me a lot because whilst Joel started slow, he got better and better. It is good because we do not know how long Fitz will be out for so it is good to have players like Joel come in and do well."
