MK Dons captain Dean Lewington is a doubt for Tuesday's game against Hereford United.
Lewington was given an x-ray after an ankle injury sustained whilst playing against Walsall yesterday.
"I'm a bit disappointed to have lost our skipper," said manager Roberto Di Matteo.
"We've sent him for an x-ray so we just have to hope and keep our fingers crossed that it's not too bad.
"It's on his ankle but I don't think it was a bad tackle or a nasty challenge, it's just one of those normal football tackles."
Dons won the game 3-0.
