Percy Kiangebenin and Tyrique Hyde have extended loan deals away form the U's
The young duo have already spent time at Hendon and Dartford respectively and will remain at their loan clubs.
Percy will now spend the rest of the season with Hendon, and will be hoping that his goals can lift the Southern League Premier Division South side from their current position in mid-table.
At Dartford, Tyrique is staying another month as the Kent side look to maintain their place in and amongst the promotion contenders.
U's Director of Football Tony Humes said: "Both clubs wanted to keep the boys, and we were happy with them continuing their football development by being involved in competitive men's football."
