Goalkeeper Matt Ingram will remain at Blue Square North side Oxford City until the end of the season.
Ingram, 19, has been in fine form since arriving on loan in late October, keeping five clean sheets in nine games.
“I’m really enjoying it,” he said. “I feel like I’m growing up in the game - I was perhaps a bit shy before but I feel like I’m coming out of my shell.
“Hopefully I can get as many games as I can and keep on developing.”
The deal includes a 24-hour recall clause.
