U's waiting on Smalley
Oxford boss Chris Wilder is hopeful forward Deane Smalley will be ready in time for the cup clash with Gateshead.
The 25-year-old has missed his side's last three matches with a groin problem but is likely to return to the matchday squad on Thursday, while Sean Rigg (hamstring) is still out.
Wilder, who was given permission to speak to Portsmouth about their vacant managerial position earlier in the week, remains without a host of players.
On-loan Shrewsbury defender Asa Hall is ineligible and long-term absentees Andy Whing, Alfie Potter and Jon Meades (all ankle) are still sidelined.
