Histon have sealed the loan signings of Crystal Palace goalkeeper Wes Foderingham, Luton defender Ed Asafu-Adjaye and QPR winger Elliott Cox.
Cox, 19, had a one-month spell with Ryman Premier Division side Tooting earlier this term.
Versatile 22-year-old defender Asafu-Adjaye has made four Hatters appearances this season.
While Foderingham, 20, fills the hole left by Joe Welch's departure to Stevenage on Thursday.
All three have joined until the end of the season.
The Stutes have made the signings just 24 hours after having an 11-week transfer embargo lifted.
"I'm delighted to welcome all three lads to the club," boss David Livermore told the club website.
"It was important to move quickly on the last day of the loan window after the embargo was lifted yesterday and Joe moved to Stevenage.
"I hope that this shows our intent to do all we can to stay in the Blue Square Bet Premier and we are very much up for the fight to sustain our league status."
