Aaron Henry has been recalled from Crawley Town and will spend the second half of the season on loan with Wealdstone.
The 20-year-old midfielder made 17 appearances for the Red Devils, 13 of which came in Sky Bet League Two.
The academy graduate now returns to Wealdstone, where he enjoyed a successful spell during the latter part of the 2021/22 campaign.
Meanwhile, U21s defenders Jacob Roddy and Seydil Toure have both joined National League side Oxford City on one-month loan deals and U21s winger Tolu Ladapo has signed for National League South outfit Hungerford Town on a month-long loan.
