Rob Edwards' small squad currently has three known injury concerns, but who will be available to make the trip to London?
Angel Gomes - 90% chance
The recent signing came off after 20 minutes against Arsenal with a back complaint and Edwards was unable to give an update after the game in midweek.
But the midfielder will be available on Sunday.
"It locked up, I think he had a spasm, but he's trained today and is available," Edwards said.
"We have a few walking wounded, and some we have to check on to see how they are tomorrow.
