Blackburn midfielder Tugay will be out of action for about a month after injuring his knee in training.
A scan revealed the 34-year-old Turkish international suffered damage to a medial knee ligament.
He is likely to miss all six of Rovers' Premiership matches over the forthcoming festive period.
David Thompson - who has himself just returned from 14 months out injured - or Garry Flitcroft will replace Tugay at Crystal Palace on Saturday.
