Ross Barkley is making progress in his recovery from injury but the on-loan Aston Villa midfielder will not be fit in time for Saturday's midlands derby against Wolves.
The 27-year-old, on a season-long loan at Villa Park from Chelsea, sustained a hamstring injury early on in the home defeat to Brighton on November 21 and missed the loss at West Ham last week.
Dean Smith's side resume their Premier League campaign at Molineux on Saturday and Barkley will remain on the sidelines, although it is hoped he could return against Burnley next week.
