CRYSTAL Palace midfielder Jonny Williams has suffered another setback through injury.
The Wales international has had a problem with his groin in training today but it is believed he has only slightly aggravated it.
Williams had only just returned to full training this week and will be closely monitored in the next few days.
Boss Alan Pardew said: "Jonny has had a slight problem today which has probably knocked him back a little bit.
"I can't give a date (on when he might return). It's a slight groin strain I think he had today."
