U's sell out FA allocation
Only a handful of tickets remained on Wednesday morning and they were snapped up before 9.30am.
Season Ticket holders snapped up around 800 of the U's allocation for the fixture at Melbourne Park, before tickets went on general sale on Tuesday night.
Away tickets for U's FA Cup clash with local neighbours Chelmsford City have sold out.
He already had MK Dons' permission for Jabo Ibehre to play but had to wait until this week to get the go ahead from Arsenal for Craig Eastmond and Sanchez Watt.
Wednesday morning also bought the announcement that U's boss could pick all three of his loanees for the clash.
With Chelmsford expected to sell out their home areas as well, a capacity crowd of over 3,000 is expected on Saturday afternoon.
