West Ham striker Rob Hall has extended his loan stay with Oxford for another month.
The 18-year-old first arrived at the Kassam Stadium in September and has scored six times in 11 starts for the U's.
Manager Chris Wilder told Oxford's official website: "We are delighted to have Robbie here for a further month at least. He gives us something different up front, is a proven goalscorer and has fitted in really well here. It speaks volumes about our set-up that West Ham are happy to let him continue his footballing development with us."
