The Bulls have had chance to rest this week after postponing their game against Frome.
The team trained yesterday as normal, and will do so tomorrow and Friday as well.
"We'll train Thursday, make our way up Friday and train then as well.
"We'll prepare as best we can, but if the players give me what they've given me today then we can only be proud of what they've done and achieved.
"If we play like that [like Oxford on Saturday], then who knows what might happen?"
Calvin Dinsley and Pablo Haysham might be back from injury, but Tyrone Duffus and Mike McGrath won't.
Cameron Pring and Eliot Richards are both unavailable as they're cup tied.
