The 24-year-old returned to the West London club for treatment on his foot problem earlier this week, despite having his initial one-month loan spell extended by two months the week before.
The former Chelsea player had been playing with the bone fracture in his foot and was unaware that the injury was serious.
However, the pain became such a problem that the left back needed an X-ray, which revealed the break.
The news will come as a blow to Fulham, and especially Sheffield United, with Blades boss Neil Warnock in need of finding new faces following a recent injury crisis at Bramall Lane.
