Midfielder's ever present League run could end
The midfielder was forced off just past the hour after taking a kick in the defeat by Wigan last weekend and has not trained this week.
“Cole is struggling for Saturday and he could be a concern for the Derby game next week as well,” Town boss Mick McCarthy told the Club website.
“He has been a terrific signing for us and I think he has played in every League game and that might be the problem. Maybe that has taken its toll.”
Frank has been sidelined with a hamstring for the last few weeks but has returned to training and should be okay for Saturday’s trip to the Amex Stadium.
