Luis Morrison-Derbyshire, one of the 46 players used this season by Jon Taylor, has joined Grays Athletic.
The Ryman League side is his fourth of the season, having had brief stints at Maidenhead and Hampton & Richmond since departing Edgar Street in early September.
The defender has already seen a managerial change, with Jody Brown leaving Grays to become Welling's new boss. Club owner Andy Swallow, an occasional visitor to Edgar Street earlier in the season, has decided to take temporary charge of the side himself.
