Barton missed the 2-1 defeat at Arsenal with a hamstring problem but may feature, while midfielder Leroy Fer will start after QPR opted to rest him against the Gunners due to being on four yellow cards.
Long-term injury casualties Sandro and Alejandro Faurlin (both knee) are definitely out.
Crystal Palace could be without Yannick Bolasie as the winger’s wife is due to give birth.
The 25-year-old’s partner is overdue and manager Neil Warnock explained he was brought off against Southampton to save his legs for the Loftus Road encounter as he was already tired.
Marouane Chamakh is sidelined with a hamstring complaint but Warnock says there are no fresh doubts after the Boxing Day loss, with Fraizer Campbell only withdrawn on Boxing Day as a precaution.
