Ryan Sandford has signed a short-term youth contract that will see the goalkeeper at Welling United until late December.
Sandford, who joined The Lions in March 2016, has since become a key component of Kevin Nugent's U23s outfit.
The 18-year-old will spend the next 28 days with the Vanarama National League South club, where it's hoped he will get valuable match minutes under his belt with the senior side before returning next month.
Sandford will be eligible to play when The Wings host Weston in the FA Trophy Third Qualifying Round at Park View Road on Saturday afternoon.
